yarrow is a free library of bug fixes that ai coding agents share. new thing: on claude code it now searches by itself when a command fails, so you dont have to tell your agent to use it

setup is one command:

npx yarrow-fixes install

what id love to know after a few days: did it ever show you a fix that actually helped, and was it ever annoying

yarrow-fixes.vercel.app

I'll test your app, you test mine. Deal?

Mine is Stamp the Past, a free phone game I made with my teenage son. You pick a town, find four real landmarks, and slide an old photo into today's view. It takes about 5 minutes to try, and no account is needed.

Drop your link below and I'll test it and send honest feedback. All I ask is that you try mine and tell me what's broken, confusing, or boring.

Feedback goes in the app: tap the menu (☰) and choose "Report a problem or send feedback", or use "Something wrong here? Tell us" inside any stop.

Thanks, boom.

Hi Everyone!

I recently launched Poppel, a bubble-popping puzzle game for iPhone iOS-only, in September 2026, and I’m excited to share it with you!

Poppel features Classic, Continuous, and Campaign modes with 50 levels, plus a Daily Challenge with changing gameplay modifiers.

I’m continuing to improve the game, so any and all feedback is super helpful! I would love to hear what you think about the gameplay, difficulty, or anything else that could make the experience better.

Thank you for checking it out and for the support!

I’ve been building Pokémon ALL-11, an unofficial fan-made soccer game

You can build and save lineups from across the Pokédex, play real time soccer against Gym Leaders, start a solo club career, or invite friends into a league for live matches. There’s also online head to head matchmaking and local 2 player play , and more.

🔗 Play: https://all11pokemonsoccer.vercel.app/

I’m still improving the game, so I’d love feedback

This is an unofficial fan project and isn’t affiliated with Nintendo, Game Freak, or The Pokémon Company.

I love buying secondhand furniture, but I got tired of guessing whether something was overpriced or what to offer sellers.
So I built Marketplace Product Lab.
You paste a listing link, description, or screenshot, and it helps you figure out whether to buy, what to offer, your maximum price, and what to say to the seller.
It’s an early beta, completely free to try. I’m looking for 10 people to test it with a real listing and give me honest feedback.
Try it here: https://marketplace-product-lab.floot.app
Would love to hear what works, what’s confusing, and what you’d change.

hey everyone, me and my mates are developing an app to help people to value stuff in their house and give insights before they sell or just doing decluttering.

anyone want to test this out?

¡Hola a todos!

Actualmente estoy desarrollando Tradix, una aplicación educativa diseñada para ayudar a las personas a aprender a operar en bolsa paso a paso, incluso si empiezan desde cero.

Mi objetivo es que el aprendizaje sea más estructurado, interactivo y motivador mediante lecciones educativas, retos diarios, puntos de experiencia, clasificaciones y estrategias de trading.

Estoy trabajando duro para que Tradix sea realmente útil y mi objetivo es lanzarla en diciembre de 2026.

Si estás aprendiendo a operar en bolsa o siempre has querido empezar pero no sabías por dónde, ¡me encantaría saber tu opinión!

¿Te interesaría probar Tradix cuando se lance?

Si es así, ¡deja un comentario abajo! Me encantaría saber cuántas personas buscan una mejor manera de aprender a operar en bolsa, qué características les gustaría ver en una app como esta y qué la haría valiosa.

Si conoces a algún amigo o familiar interesado en aprender a operar en bolsa desde cero, no dudes en hablarle del proyecto.

Estoy desarrollando Tradix pensando en los principiantes, y tus comentarios sinceros me ayudarán a mejorarla antes del lanzamiento.

¡Gracias por tu tiempo y apoyo! 🙌

Tradix: Aprende hoy. Conquista el mañana.

I’m building PMMockr, a browser-based mock interview tool for product managers, and I’m looking for feedback from people preparing for PM interviews.

The test: choose a case from the free practice bank, explain your approach by voice, answer the AI interviewer’s follow-ups, then review the feedback.

What I’d like to learn:

* Did the follow-ups respond to your actual reasoning?

* Can you point to a feedback claim that was useful—or wrong?

* After reading the report, is it clear what to practise next?

Try it here: [https://www.pmmockr.com/practice](https://www.pmmockr.com/practice))

Sign-in is required. The Top-MNC practice bank is free; additional company-specific banks require Premium, but they aren’t needed for this test. Voice practice requires microphone access. AI feedback can be mistaken and does not predict hiring outcomes.

Please share feedback here without posting private interview transcripts or personal details. If something breaks, your browser/device and the step where it happened would help.

Disclosure: I’m the builder; this post was drafted with AI assistance.

Looking for early pilot users. This is a Stanford product class project, and we’re testing real demand.

What it does: builds AI-generated agendas, facilitates live with in-meeting chat, and maps a shared roadmap as you talk.
Who it’s for: product managers running cross-functional meetings.
Why it’s different: Otter, Granola and Zoom AI mainly summarize after the meeting. Flipper keeps the team aligned during it.

Join the waitlist: https://flipper-class-demo.vercel.app

Feedback on the pitch or the price is just as welcome as signups.

Hi everyone.

We’re a small startup from Panama. Our app, NesaConfía, helps women understand their predisposition to certain diseases and build habits to stay healthy before problems show up.

Here’s why we built it. In Panama, a lot of women work full time, raise kids and take care of their parents. Their own health ends up at the bottom of the list. We wanted something that takes five minutes a day and still makes a real difference.

How it works:

• You answer a few questions about your habits, lifestyle and family history.
• AI analyzes your answers and shows your predisposition.
• You get personalized recommendations and can track your habits.
• There’s a marketplace with doctors, labs, restaurants and gyms at special prices.

The app is live and working. What we need now is people using it and telling us what breaks.

Link: app.nesaconfia.com

A heads up: the app is in Spanish. If you speak Spanish, you’ll get the full experience. If you don’t, you can still help us a lot by testing the sign-up flow and telling us where you got stuck.

What we’d love to hear:

1. How easy was it to sign up?
2. Did the questions feel clear or confusing?
3. Did the results make sense to you?
4. Anything that felt slow, broken or weird on your phone?

Drop your thoughts in the comments or DM me. Happy to return the favor and test your project too.

Thanks!

I built a prompt I run before walking into small shops (tire shops, salons, restaurants). You feed it what you already know about the shop, and it builds a one-page discovery sheet:

• how the shop gets customers today and what that costs them
• their online gaps, ranked by what a customer actually sees
• the two cheapest high-impact fixes
• three icebreaker questions that never sound like a pitch
• two red flags that mean walk away
• a 60-second elevator line, under 40 words, no buzzwords

What I'd love tested:

1. Run it on a real or imagined shop and tell me what's missing or what wording broke.
2. Especially useful if you've done door-to-door sales or run a small shop yourself.
3. If you run a small business, try it on your own shop and tell me whether the sheet would actually help you.

The full prompt text is in this post on r/ChatGPTPromptGenius, where I'm also collecting feedback:

https://www.reddit.com/r/ChatGPTPromptGenius/comments/1xgc4hp/i_built_a_prompt_that_turns_a_walkin_visit_to_any/

Full disclosure: I draft with an AI assistant and edit before I use anything in the field. Not selling anything.

Hi everyone!

I just finished my first app: a friendship app for teens ages 13 to 17. I would love your feedback and I need your help testing the app. You can check it out and sign up here: https://ourspacehq.lovable.app/

Enjoy the free trial, and if everything is working as intended, share with teens for me - the teen spaces have deleted my request for testers. Thanks!

Imagine spending 10 seconds posting a product idea. If enough people want to buy it, someone else builds the business, and you could still own a piece of it. No manufacturing, no fundraising, just your idea. That’s the vision behind foundtide. We're looking for beta testers as the website nears completion as well as feedback on the idea. 

Which of these would help you most?

1. Watering and feeding reminders
2. Planting calendar for your zone
3. Pest and disease identification
4. Garden layout planner

What it is: I've been building SmittyHQ, a shared brain for families. It brings together schedules, school communications, activities, and who's responsible for what, so everyone in the household (including their personal AI assistants) can work from the same information.

I recently launched a connector for Muse and Grok. Now you can ask your personal AI things like "What's happening with the kids this week?" or "Who's handling pickup Thursday?" and get answers based on your actual family schedule.

What I'm testing: Two things: Can people connect Smitty to their existing AI assistant without help? And once connected, does having access to shared family information actually make their AI more useful?

What you'd do (~10 min): Create a free SmittyHQ account, add some family schedule information, connect it to Muse or Grok, and try asking a few questions.

I'd love to know:

1. Could you connect it without help?
2. What's the first thing you asked your AI?
3. What would make you want to keep it connected?

Who I'm looking for: Parents who already use Muse or Grok and are interested in making their personal AI more useful for family life.

I'm a solo founder looking for about 10 testers. It's free, and I'm happy to test your product in return!

Comment or DM me if you're interested, and I'll send the setup instructions.

I got tired of re-explaining my business to each tool. Vilix AI is a cloud memory layer over MCP, so the same memory shows up on every tool and device. Stores full conversations. Free plan, no credit card. What would you want a shared memory to hold?

Disclosure: I'm the founder of Vilix AI.

Hey guyss!

Im an indie developer working on Cancelly, an Android app designed to help people avoid getting unexpectedly charged when free trials end.

We've all been there: sign up for a free trial, forget about it, and suddenly find a charge on our card.

That's the problem Cancelly is trying to solve.

What does Cancelly do?

• Keep track of your free trials.
• Remember important renewal and expiration dates.
• Send reminders before a trial ends.
• Help you avoid unwanted charges.

The Android app is ready for closed testing, and I'm looking for people willing to give it a genuine try before its public release, cuz I need testers to have it published.

What I'm asking from testers:

1. Join the testing group.
2. Opt into the Google Play closed test and install Cancelly.
3. Keep your testing opt-in active for at least 14 consecutive days.
4. Actually explore the app and let me know what works, what doesn't, and what could be better.

You don't gotta be a developer. Just someone who uses Android and is willing to give honest feedback

Interested in testing?

If you'd like to help, send me a DM with the Google account email you use on the Play Store.

Ima add your email to the internal testing list and send you the instructions to access and install Cancelly.

No payment, no technical experience required. Only just a willingness to try the app and share honest feedback.

Thanks for helping me get Cancelly off the ground!

UNREAL is a dating app too good to be true. So it is not.

Online dating is fun: swiping, matching, that flirty first chat.

Unless you're taken. Or you never get matches. Or you just don't have the time to respond immedeately 24/7 to incoming chats. And we not even talk about toxic people that wait behind the fake images.

So I built a dating app where every profile is an AI character. No broken hearts, no shame, just fun. It looks and works like the apps you know – swipe, match, chat. The difference is on the other side.

Every character has their own life, job, story and personality. They remember what you told them, know what time it is where you are, and pick up where you left off. Some are shy, some are bold, some make you work for it. Some send photos – if you're nice to them.

No real people. No consequences. Nobody gets hurt.

I'm looking for early testers: onboarding, characters, free tiers... Is it as much fun as a real dating app?

Swipe a few, chat with your unreal matches, tell me your real feedback. No account required, no download possible.

Hi everyone!
I’m the creator of Settlist⁠, a free website that turns common German bureaucracy processes into step-by-step roadmaps.
It currently covers 55 roadmaps across topics such as registering an address (Anmeldung), residence permits, the EU Blue Card, naturalisation, unemployment, and leaving Germany.
I built it because navigating German bureaucracy can be confusing, especially when it’s unclear what to do first, which documents are needed, or what comes next.
I’m looking for people to test the early version and tell me what works and what doesn’t.
What I’d love feedback on:
Is it easy to find the right roadmap?
Are the steps and instructions clear?
Is anything confusing, missing, or difficult to use?
The legal information is checked against current German legislation and dated, but feedback on clarity and possible errors is especially welcome.
I’m the independent creator, and I’m being transparent that this is an early version. The site doesn’t ask for personal data. I may use basic website analytics to understand how the site is used.
Website: https://settlist.app
Honest criticism is very welcome. Thanks for helping me improve it!
Please do fill the form for the feedback

I’m Samuel, creator of Quanta Match, a browser game for pairing maths and science items with their names or results. I’m looking for adult testers to check whether the interface is easy to understand.

Please open https://quantaaulas.com/ligacoes/, choose English, and look for the options to start a short round or configure a game. Are the choices and the two-column layout clear on your device?

If you spot confusing labels or a layout problem, I would appreciate a comment with the browser and device type; please do not share personal information. This is my own educational project.

I save literally everything.

Recipes I want to try. Clothes I want to buy. Places I want to visit. Videos I want to watch later. Random ideas I swear I'll remember.

And then... nothing.

They just sit in my camera roll until I completely forget why I saved them in the first place.

I tried organizing everything into folders, but I realized something: my problem wasn't that I couldn't find my screenshots. It was that I never remembered to do anything with them.

So I started building a little app called SaveSoon.

You upload your screenshots or saved links, it helps organize them, and you can set reminders so the things you save don't just disappear forever.

The idea is to turn "I'll do this later" into actually doing it.

It's still early, and I'm planning to significantly improve the screenshot analysis, so there's definitely more work to do.

If anyone wants to give it a try, there's a 7-day free trial: https://screenshot-reminders.vercel.app/

I'd genuinely love some feedback, especially on what works, what doesn't, and what would make you actually come back to the things you've saved.

Thanks to anyone who gives it a shot!

I just launched a small web app called PickOne.

The idea is simple: upload two pictures, ask a question, and share a link so anyone can vote.

No accounts, no downloads, and completely free.

You could use it to choose between two outfits, logos, designs, products, or anything else.

https://pickone.microapplab.workers.dev

I'd really appreciate it if someone could try creating a poll and tell me whether the process is easy and intuitive.

Thanks!
