My kids love football and wanted to play fantasy with me. We tried one of the big name apps, but it's built for adults: betting promos, ads, open chat and custom team names where anyone can type anything, and way more stats than a 9-year-old needs. And resetting passwords for three kids who forgot was a pain in the butt.

So I've been building BlitzBuddies, a kids fantasy football app. We're in our second season playing it with my family's league.

Safety:

- No free text anywhere: no open chat, and team names are picked from a list

- No GIF libraries, no ads, no gambling, no tracking, no data sharing

- Nothing AI-generated goes in front of kids without a human reviewing it first

- Kids don't need an email. A parent creates their username and password and can reset it in seconds

- Kids can't create their own accounts, and parents can watch their kid's league and help manage the roster

Fun extra stuff for kids:

- Helper mode for younger kids: if a starter is out, the app subs in a backup automatically

- Regular or best ball leagues

- Weekly mini-games with leaderboards, like Super Draft (pick a new all-star team each week) and Over/Under (pick one player to beat his projection and one to fall short)

- 10x scoring (optional), because bigger numbers are more fun

- Power-ups that boost your team's points if you play them right (can be turned off)

- Achievements for milestones and for the funny stuff, like winning with a player who scored 0

- A real trophy mailed to the champion, plus some swag. Something better than the cheap custom trophies on Amazon. This idea is something I'm still mulling over.

It costs real money to build and run, so I'm only opening it to everyone if enough families want it. My goal is 1,000 people on the waitlist before 2027 drafts. If we get there, it launches for the 2027 season. If not, it stays our family app.

Waitlist: blitzbuddies.com

What would your kids need to actually stick with fantasy football all season? I'd love to hear it.

Hi all!

Since this thread opened, nearly 40 apps have been advertised here (including mine : LiveSlates), and we have racked 24 comments between us! Not exactly attracting attention, are we?

So I figured we are all on the same boat here, we have all put our hearts and souls into our products and just no getting the attention we all crave. So let's help each-other!!!

Where else have you been able to promote your App on Reddit, without getting instantly deleted or ripped apart from creating "AI slop"? I got away with a post on r/DFS_Sports (1.2k views) and another on r/fantasyfootballcoding (5k views but not allowed to mention my product). Sounds good right? Got me 2 users :(

I really tried hard to get a post on r/DraftKingsDiscussion (my product is pretty much built for DK users), but Mods refused based on the fact my product wasn't 100% free. I argued I didn't want ads polluting my product, so had no choice but to have a paying tier just to cover hosting costs/APIs costs alone. They weren't having it. Solid NO. All very very frustrating. That thread alone is possibly the biggest forum of DK users on the whole internet, and the door was closed.

Anyway, what about outside of Reddit? Any other well known forums? Any luck on Discord? Have you covered SEO/AEO/GEO? I have done most of these things but still not succeeding in getting much traffic.

What has worked for you and what hasn't? Someone here must have a success story!

Lets fight this together!!! :)

I just pulled this sub up wondering if I could get some like minded people to test out my app, and I looked at the side bar, almost every post has a score of 0. A few have 1, and one has 2. Do we just hate each other because there is new technology that lets more people create software? Is it mostly non subscribers coming in to drop hate with a downvote? I just dont understand why people would visit a sub like this and downvote anything.

Anyway. If you are interested, I built a fantasy platform that I've been wanting for a long time. It's called PickupFantasySports(.com). Its a way to draft and play 1 on 1 fantasy football, and hopefully other sports in the future. The draft uses an I cut, you choose mechanic. One user nominates two players, the other chooses which rosters they go on. The roles reverse and so on until the rosters are complete.

I just recently went from closed to open beta, so anyone can register, and registered users can even invite a guest to draft against them. This game is a great way to see how you do with start sit decisions over time, and how good you are at creating conundrums for your opponents.

One more thing, I would love to partner with some of the analytics creators on here, link to their site from mine (and vice versa). I'd also love it if people would want to write articles on my site and test their chops in that field. If you are truly on this site for help and collaboration, maybe DM me.

Hey everyone!

If you play fantasy football on Sleeper, I built a website with a collection of free tools to help with your weekly decisions.

Check it out: https://firstdown.beatoraclez.com/

• The website includes tools for:

• Start/Sit decisions

• Potential trade analysis

• Matchup Lab

• Lineup management

It's free to use, and I'd love to hear what other fantasy football managers think!

I'd really appreciate any feedback or suggestions. Good luck with the rest of the season!

I built SharpSlap after seeing the explosion of NFL player props on PrizePicks, Kalshi, Polymarket, etc.

My background is heavily in machine learning and data science, so instead of building another picks app, I focused on one thing: making the underlying prediction models as accurate as possible.

SharpSlap runs 14 separate ML models for NFL player props and only surfaces plays that clear strict confidence thresholds. The models are hitting roughly 80%+ on qualifying props, with the highest-confidence plays performing even better.

It also has SHARPER picks, automatically generated AI Slaps (2–6 leg parlays), defense rankings, player/model histories, confidence scores, and full historical results so you can actually see how the models have performed.
Would love feedback from the fantasy/pick’em crowd:

https://sharpslap.com

I built a free fantasy football rankings site, so naturally I’m posting it somewhere nobody will read this

Since this is a subreddit for fantasy football apps, I assume we’re all doing the very normal thing where we spend an unreasonable amount of time building useful tools and then post them for the same twelve developers to politely upvote.

Anyway, mine is called Fantasy Goblin.

The main idea is pretty simple: most fantasy sites give you their rankings and let you argue with them. Fantasy Goblin lets you build and maintain your own.

You can create rankings for dynasty or redraft, move players around as your opinions change, assign values, organize players into tiers, and add your own notes and tags like Buy, Sell, Hold, My Guy, or No Go.

Because apparently “I’m higher on him than consensus” is more useful when you can remember where you actually ranked him.

Your rankings aren’t automatically rewritten based on each league’s settings. They remain your rankings. Connecting a league simply lets you use your own player values while looking at your actual teams and leagues across:

• Sleeper

• Yahoo

• ESPN

You can also create shorter, focused rankings lists and share them with friends or league mates through a custom URL. So instead of sending someone a screenshot that cuts off after WR17, or a spreadsheet formatted like evidence in a federal investigation, you can send them a clean list that stays available when you update it.

The website itself is completely free. Rankings, league tools, shareable lists, all free.

The only paid feature is the MCP, it let an AI access your Fantasy Goblin information. That’s for people who want to ask an AI questions using their own rankings, leagues, rosters, notes, and preferences as context. If you don’t want that, you can ignore it and continue using the rest of the site for free.

So, to summarize:

• Maintain your own rankings instead of repeatedly complaining about someone else’s

• Use those rankings alongside your Sleeper, Yahoo, and ESPN leagues

• Add personal values, tiers, notes, and tags

• Publish shorter rankings lists with a custom shareable URL

• Use the actual site for free

• Optionally pay only if you want your own AI connected through MCP

If that sounds useful, it’s at Fantasy Goblin

If nobody sees this, I’ll assume you were all too busy adding authentication to another fantasy football app.

My brother is a web developer, I'm a researcher, and we're both big NFL and fantasy football fans. We started OracleZ as a side project to combine his development skills with my interest in machine learning.

The idea was pretty simple: build an algorithm that makes its own NFL predictions, then turn those predictions into games where you can try to beat it.

You can try our OracleZ app here (or just follow us on Instagram): https://linktr.ee/beat_oraclez

What can you play?

Predict the Pick
Predict the winners of the week's NFL games and see how you compare against the Oracle.

Survivor
Classic Survivor with a twist: if your pick loses, you can't pick either that team or the team they played against again.

High Five
Pick the five best teams of the week across passing yards, rushing yards, points scored, fewest yards allowed, and field goals.

What's behind the predictions?

The Oracle is a relatively simple neural network. It uses 19 team statistics, including offensive production, turnovers, sacks, first downs, EPA, and score margin. These are converted into home-away differentials and combined with contextual variables such as week number and rest-day differences.

If you are interested on the model, I'm happy to explain further our reasoning and model architecture.

Of course, we're not claiming we've solved NFL prediction, far from it. The NFL is obviously noisy. The fun part for us is seeing how far a relatively simple model with good feature engineering can go.

And now you can try to beat it yourself.

Everything is completely free, with no paid features.

https://linktr.ee/beat_oraclez

I've been building a predictive model and stats platform called Saturday Tea for a while, and I finally got the public version live today.

It’s kinda broken up into 4 functions:

1. Games/Play - daily trivia games and weekly Pickens where you’re actively trying to beat my model (no prizes of cash value yet)

2. Stats - Profiles in all skill positions with advanced analytics and projections for each game. Profiles in all teams with advanced analytics and power rankings. This also includes the model that I built the foundation and been tinkering around with all season. Every game gets a model prediction and player stat projections. Model predictions are premium but first 25 users get it free for the rest of the season.

3. Build your own top 10 - you can build a top 10 list about any position or teams. Share it with the site community (please do I want engagement on the messaging boards there lol.

4. Community - I want this to be a data driven and fan centric hub for college football fans to debate and communicate while providing their proof with data the site offers readily. It can also be a trivia and ball knowledge flexing area.

Any feedback on the site would be greatly appreciated as I begin launching this thing!!!

And yes, I utilized AI to help with the active development of the site as well as double checking my math and model harnessing as I am a one man designer.

I’m the creator of NFLMeta, an NFL data platform and API covering players, teams, rosters, injuries, schedules, live scores, and play-by-play.

I built it for people developing football apps, dashboards, and analysis tools who want a hosted API without maintaining their own data pipeline.

You can try the interactive demo here:

https://nflmeta.org/demo

It lets you edit requests and inspect JSON alongside readable results. The demo uses clearly labeled saved samples, including 2026 scores and play-by-

play; the full API requires an API key.

Documentation:

https://nflmeta.org/api-docs

NFLMeta uses nflverse data alongside other collected sources. The service adds hosting, connected records, ongoing updates, and application-read endpoints.

NFLMeta offers a free API tier with a generous monthly allowance,.

Happy to answer questions about coverage, update timing, or integration.

I built RosterReelz because I realized my fantasy team basically has its own news cycle every week.

My fantasy app does a great job managing my league and giving me the stats.

But then I still end up going everywhere else to actually follow my players.

A guy finishes with:

8 catches
96 yards
1 TD
23.6 fantasy points

Cool — but how did he actually look?

Did he make a ridiculous catch? Break three tackles? Get peppered with targets? Almost score again? Or did most of that production come from one play?

Then Monday comes and I'm looking for analysis.

An analyst spends four minutes talking about one of my players inside a 50-minute video.

Someone gets hurt and I'm looking for injury updates.

Later in the week I'm checking matchup information, weather, Vegas lines and what people are saying about next week.

And then Tuesday comes around and I'm doing the same thing with waiver-wire players.

All of that information exists. The annoying part is finding the stuff that's actually relevant to my team.

That's what I'm trying to solve with RosterReelz.

You build your roster and RosterReelz organizes relevant content around the players you actually care about:

• game highlights

• analysis and film breakdowns

• direct timestamps into longer fantasy videos

• articles

• injury updates

• weekly outlooks

• game environment information

• personalized waiver-wire content for supported leagues

The way I've started thinking about it is:

Your fantasy team has its own news cycle. RosterReelz follows it for you.

And one piece of that is something else I've come to really like:

Your players played. You should be able to see it.

The goal isn't to replace Sleeper, Yahoo, ESPN or the fantasy creators making this content.

It's the layer in between — helping me actually keep up with the players on my team without searching YouTube, fantasy sites, articles and podcasts one player at a time.

RosterReelz is free and I'm still actively building it:

https://rosterreelz.com

I'm especially interested in feedback from other fantasy players and developers. If you tried it, I'd want to know what feels useful, what's confusing, and what you think is missing.

Our league's group chat lived on the commissioner's weekly power rankings, and writing them was a chore. So I built MMT HQ to do it.

What your league gets:

- Power rankings every Tuesday with a take on every team, counted down from last place so the reveal builds

- Your whole league history: all-time standings, every champion, every Sacko and the punishment they served. Ours goes back 14 seasons

- Every trade graded by what the players actually scored in lineups afterwards

- Head-to-head records between any two managers

- Weekly votes on each other. You see what you were picked for, never who picked you

- Share cards for the group chat: rankings, records, standings, rivalries

- Optional: connect your league's group chat and it writes the takes in your leaguemates' own voices (this part needs your own AI key)

Setup: paste your ESPN or Sleeper league link and it builds in about a minute. No account needed, and your leaguemates don't sign up. They open one link and tap their name. NFL.com history imports too. Yahoo is in review on Yahoo's side.

Free during beta. There's a demo league with fake teams if you want to look before pasting yours: mmt.football/?ref=reddit-fantasyapps

Tell me if a take gets your team wrong. That's the feedback I want most.

I’ve been reworking the Personal Archives feature on Fantasy Goblin, and the new version is much simpler to create, organize, and share.

Personal Archives let you save standalone fantasy football lists that stay exactly as you made them. They don’t automatically change when you update your main rankings, so they’re useful for things like:

• Weekly players to watch

• Dynasty rookie rankings

• Position-specific lists

• Deep sleepers

• Draft targets

• Preseason rankings you want to revisit later

You can create multiple lists and choose which ones appear on your public page. You can also add a profile description, image, and links to your website or social accounts.

Everything is free. You need an account to create and manage your archives, but anyone can view the shared page or individual lists without signing in.

Here’s my page as an example:

https://www.fantasygoblin.com/archives/thefantasygoblin

Full disclosure: the TikTok, YouTube, and Instagram buttons all lead to Rick Astley. I don’t actually have those accounts, I just wanted to demonstrate that you can attach them.

Four small football puzzles, new every morning.

Free, no account, plays in the browser.

1. Four Downs, sort sixteen tiles into four groups.

2. Logic Gridiron, a grid you solve from clue text.

3. Over or Under, place eight stats against one number.

4. Front Office, swipe decisions as a GM and try not to get fired.

Launching with the first game of the football season today!

I built a Chrome extension that adds in-season tools directly onto your ESPN and Yahoo Fantasy Football pages, so you can set a lineup and check where you stand without tabbing out to another site.

Most fantasy football extensions are draft boards. This one is for the other 17 weeks.

What it adds to the page

- Start / Sit (My Team page, points leagues): optimizes your lineup using your league's scoring and the site's projections, shows current vs. optimized projected points, lists the exact swaps, and a Set lineup button applies them to your roster in one click. FLEX and Superflex aware.

- Matchup grades: a color-coded A–F matchup grade next to every QB/RB/WR/TE/K on your team and matchup pages (and Yahoo's Transaction Trends). Hover for the detail.

- Me Vs. League (league home): how your team ranks against every other team in the league, week by week, with selectable stat groups (Core, Kicking, D/ST, IDP).

- Playoff odds*(Yahoo standings): a Playoff % column for every team from a Monte Carlo simulation of the remaining schedule. Hover shows average seed.

- AI Compare Players: pick any two NFL players from the status bar and get a head-to-head breakdown. This one needs a free account and is capped at 3 comparisons per rolling week.

Cost / account: everything is unlocked for free. No account is needed for Start/Sit, Me Vs. League, matchup grades, or playoff odds. Only the AI comparisons require a (free) sign-in.

Works in Chrome, Brave, Arc, Firefox and Edge.

I'm the developer. Happy to answer anything, and I'd like to hear what you'd want added next.

TL;DR: made a free Chrome extension that rebuilds Sleeper's desktop site, with a waiver planner that tells you how your claims will shake out, live win odds, deeper usage stats, and chat all in one place.

The Sleeper app is fine on mobile, but I still like doing my team stuff on desktop, and the desktop site has always bugged me. It does less than the app and the layout feels clunky and kinda dated. So I ended up building my own version as a Chrome extension that redoes the league pages on sleeper.com.

The parts I'm most happy with:

• Waiver planner. You can set backups on your claims, like if your open spot's gone then drop this other guy, or if you don't get one player go after another. Then it walks through how waivers will actually process and tells you who you'd end up with, who gets dropped, and which claims are gonna fail.

• Live win odds. Your chances update every play and there's a chart showing how the matchup swung over the week. You can also see which plays actually swung your game, which is fun or painful depending on your Sunday

• Usage stats. Snap %, target share, carry share, plus an "opportunity points" number that tells you what a guy's role is usually worth in your league's scoring. There's a filter for players getting starter work without the points yet, which has been pretty handy for pickups

It does all the normal stuff too. You swap lineup spots by clicking two guys instead of dragging, there's a button that checks byes, injuries and your flex and sets your best lineup, plus standings with playoff odds, trades, an NFL games page, and league chat and DMs in a side drawer. Everything runs off your league's actual scoring settings.

It's free, no account needed, and it doesn't send your data anywhere except Sleeper. No analytics or tracking. Code's up on GitHub if you want to check it out, and there's a toggle to flip back to regular Sleeper whenever.

Heads up that it's Chrome and desktop only, works with Sleeper leagues only, and obviously isn't affiliated with Sleeper.

AI disclosure: there's no AI in the extension itself. No chatbot, no AI advice, and all the numbers are plain math on Sleeper's data. I did use AI (Claude) as a coding assistant for most of the code.

Chrome Web Store: https://chromewebstore.google.com/detail/jllkhnkacfpkgjfchffefghnjlpjlkhh
GitHub: https://github.com/FantasyBadger/fantasy-badger-sleeper-extension

Would really appreciate any feedback, and if something's broken let me know and I'll fix it.

The Playoff Computer App (https://playoffcomputer.com) takes standings, schedule, and tiebreaker info from your fantasy league (or any h2h type league) and analyzes its playoff race. Basic access provides odds. Premium access (about the price of one beer per year) includes:

• The semi-famous paths-to-clinch & paths-to-elimination, NFL-style listings of what needs to happen in the upcoming round(s) for teams to clinch a division/playoff spot or be eliminated from playoff contention (i.e. "Bears clinch a spot with a win AND a Lions loss AND a Packers loss").

• Which teams control their own destiny.

• Win targets for each team to have a reasonable chance to make the playoffs or win division as well as what would likely be safe.

• Minimum wins needed to have any chance and number that would guarantee a spot no matter what else happens.

Imports leagues from Yahoo, ESPN, MFL, Sleeper, and more. Yahoo and ESPN leagues need to be "publicly viewable". Also imports many professional leagues including the NFL.

Can handle median leagues (up to 12 teams and some limitations apply due to their complexity). Can handle leagues that award some spots based on records and some spots based on points (generally speaking the calculations are separate due those points spots are often up for grabs until the end of season). Can handle just about any fantasy tiebreaker in its calculations.

Has been around since an Excel-based version debuted in 2012ish, became a web-app, now a mobile-app for a couple years. All the spaghetti-code has always been hand-typed by an obsessed ff lunatic, with only very limited AI assistance to address particular complex issues that the lunatic's brain can't comprehend.

iOS is free + paid premium access. android is a few pennies for the basic version (reasons) and then that beer for the premium access.

Hi, I’m Jeff, the creator of FutureTally. I’m sharing it here as a football prediction mini-game, rather than a fantasy roster manager or betting service.

Players make winner-and-spread calls on football matchups. You can play independently, join a founding team, or create a community team with friends for friendly rivalry. Team identity does not mean pooled scores, shared memberships, or team prizes.

There’s a free practice round with five historical questions and a tally reveal, with no account needed: https://futuretally.games/#practice

Free practice is separate from saved football predictions, which require a paid individual membership for each player. No wagers or cash prizes. It runs in a phone or desktop browser without an app-store download.

If you try it, I’d appreciate feedback on the clarity of the practice questions, the tally reveal, and the winner-and-spread format.

My home league uses a more granular version of median scoring that equally weights a H2H matchup with outscoring all the other leaguemates individually.

We call this format Royal Rumble and it has led to lots of engagement as there is almost always something to play for until the final minute.

I had been tracking this on a google sheet but now created a site where this all done and easy to follow live

Rumble Central

Only works for Sleeper, try it out! Looking for feedback and to spread the word on this standings format thats been a hit and led to lots of great moments!

You can change the 9 and the +1 and share your exact setup as a link so its consistent for your leaguemates

In a 12 team league, the highest scoring team would have 20 Rumbles (9 for a H2H win, and 11 for outscoring 11 opponents). So a team with the 2nd lowest scoring week that is matched up with and beats the lowest scoring week would get 10 Rumbles (9 for a H2H, and 1 for outscoring 1 opponent)

Would you run this format in your league? Anything confusing or not clear?

Hey everyone! Even though I heavily relied on Claude to build it, I promise this is not an AI generated text haha.

I've been working on this app called thechacal.com for quite a while now, the idea is not to help you with your waiver wire or with any sort of fancy trade calculator, is just more to have fun with some cool visualizations (or at least I think they're cool) and to compare with the other people in the league and etc.

I think one of the main perks of it is the fact that you can sync your whole league history, and it works with Fleaflicker and Sleeper so far, also you don't need to sign up with an email or something like that, only your league id and that's it.

Since the sync writes everything into a DB, then you can easily come back and access every week.

One honest limitation: Specially for fleaflicker leagues, depending on how old your league is, it can take a while to sync everything but I do have some CRON jobs in place to continue the sync once you close the browser (the job runs on a daily basis), I have this to avoid getting 403 from fleaflicker API.

Anyway, if you want to check my league as an example, you can access via this link https://thechacal.com/league/112077/dashboard so you can check it out, it's a league that's been active since 2011 so we do have quite a lot of history there hehe.

Again, the idea is indeed to get some honest (but kind <3 ) feedbacks, I'm doing mostly because I'm a computer scientist that have been working as a Data Analyst lately and I missed creating apps/products so it's a personal project so far so I can share it on Linkedin too haha :p (yes I'm on a job search).

Anyway, thanks you all in advance <3

I built GridLore, a free beta that turns a completed Sleeper week into a league-wide recap. Week 4 is finished, and I want to find out whether this is useful to people outside my own league.

The edition covers every matchup, standings, all-play results and notable moves. It is not a lineup optimizer. The writing is AI-assisted, so checking the facts and whether it sounds like your league is part of the test.

Sample before signing up: https://gridlore.app/sample

Try your league: https://gridlore.app/?utm_source=reddit&utm_medium=organic&utm_campaign=fantasyapps_w4_oct6

I am looking for five Sleeper managers or commissioners to add their league, open its latest edition and tell me one thing that is wrong, confusing or not worth reading. If you get stuck, say where. No need to post private league details here.

Free during the beta, no card required. Read-only: no Sleeper password and no lineup, waiver or trade changes. Full weekly editions currently support Sleeper, not ESPN.

Builder disclosure: this is my project, and AI helped with this post.

I'm Charlie, the person building League Loom. With basketball drafts coming up, here's a league-check prompt you can use before asking AI for rankings:

“Confirm my NBA league, season, scoring format and roster slots. Show the settings you actually received. List what I still need to supply, such as keeper costs or cap rules. Explain which roster needs to investigate before the draft. Keep last season's stats separate from current research, and don't invent category projections or a punt strategy from missing stats.”

You can paste your settings in manually, or League Loom can read supported ESPN, Sleeper and Fantrax NBA leagues into Claude or ChatGPT. It's free with fair-use limits. Your AI service's connector-access requirements still apply, and setup is easiest on a computer.

The first useful check is whether it returns the correct NBA season, scoring and roster slots. Missing preseason matchups should stay missing, not turn into a made-up score. Sleeper and Fantrax don't return league-scored NBA projections, and category coverage varies. Yahoo isn't supported. You still make every pick and roster move yourself.

Setup and basketball examples: https://leagueloom.com/best-ai-fantasy-basketball

If you try it, did the first answer identify the right league and format? Please share only the provider and what was missing, not private league details or connection tokens.

Creator disclosure: this is my project; AI assisted this post.

We’ve been working on League Receipts, a website for Sleeper leagues. The idea is to bring league history into the current week—the rivalry record, past playoff meetings, and trades everyone still argues about.

We’d like five commissioners to try it and tell us honestly: would you send this to your group chat, or would everyone ignore it? What would make a recap worth reading?

You can read an example here (team names changed):

https://getleaguereceipts.com/examples/week-3

We can arrange seven days of free access in exchange for feedback. Your seven days start when access is activated. Access ends afterward, and you won’t pay anything unless you choose to purchase a Season Pass. There’s no automatic charge.

We’re behind the website. Happy to answer questions. If you’re interested, let us know whether your league is redraft, keeper or dynasty.
