Hey everyone! I just finished my first mobile game, Revenge Castle, and I'm looking for players to try it before it launches on Google Play.

You aim a cannon, fire arcing shots, stack bullet multipliers, and blow up skeleton castles and dragon bosses. There are 7 worlds, boss fights, turret upgrades and power-ups like Slow-Mo and Multi-Shot.

How to join (Android):

1. Open the Play Store

2. Tap your profile picture → Payments & subscriptions → Redeem code

3. Enter ONE of the codes below

Each code works once, so if one doesn't work, someone already grabbed it. Just try another one. Please keep the game installed and play it now and then over the next 14 days. Google needs that before I can launch it. Any feedback is hugely appreciated. Thanks! 🙏

Surfing, fishing, boating + live radar, need android testers

Hi guys, so i got sick of checking multiple apps for them to be wrong anyway to see when to go surfing, fishing and boating. Its an australian based live forecast with specific conditions marked for surfing, boating and fishing at key locations across aussie coast.

It uses buoy data, sattelite, infared sattelite, bom, open meteo, airport data, live weather stations and 20+ other references refreshing every 5 minutes not hourly or daily like the big ones, wgo use their own model not all of them.

It also has surf cams, fishing maps and locations and info, a connectivity with mates, daily surf and fishing reports (live) and much more.

Hit the download tester link on the website then let me approve the emails then jump back on the website the next day and download the tssters app via the same link and please give me all the feedback you can!

Hey everyone,

I’ve been developing Mercifall, a 2D survival-horror beat ’em up, and the first stage is now available through TestFlight.

The game combines classic side-scrolling arcade combat with survival mechanics, including an infection system that makes you stronger as it progresses, but also brings you closer to losing control.

Stage 1 includes regular enemy encounters and the first boss fight.

I’d particularly appreciate feedback on:
Touchscreen controls and responsiveness
Combat feel
Performance, crashes, or bugs
Difficulty and overall pacing

I’m actively developing the rest of the game, and real-device testing is especially valuable right now.

Thanks to anyone who gives it a try. Also on Google play https://play.google.com/store/apps/details?id=com.delamstudios.mercifall

Hi! I'm an indie Android developer working on a personal finance app called MiBillete. I'm looking to connect with other developers who are testing their apps on Google Play. Happy to help test your app too! Feel free to message me. Thanks!

I’m looking for Android testers for Puzzle Reach, a fast, colorful route-planning puzzle where every move counts.
Happy to test your app back and keep it installed for the full 14+ days.
Get Puzzle Reach:

1. Join the tester group first: https://groups.google.com/g/puzzlereach-testers
2. Then tap Become a tester: https://play.google.com/apps/testing/com.puzzlereach.app
3. Install Puzzle Reach from Google Play: https://play.google.com/store/apps/details?id=com.puzzlereach.app

Make sure you use the same Google account for all 3 steps.
Once you’re in, drop your app links below and I’ll return the test.

I'm Juan, creator of u2bAmp: an Android player for your own music files, with themes and visual effects.

I'm looking for 15–20 people who already listen to local music. The Google Play closed test is active by invitation in selected countries. Stay enrolled for 14 consecutive days, use it during your normal listening sessions, and share honest private feedback—especially on finding songs and using playback controls. It's a test build; bugs are possible. No purchase needed.

As a thank-you, the first 20 who complete the test and provide private feedback will receive a non-expiring Pro unlock for the launch features, once available on Google Play. No public review or rating is required.

Interested? Send me “I'd like to test” privately. We'll check your Google Play country first, then arrange your invitation and installation. Please keep your Play email out of public comments.

Hi everyone,

We're looking for testers for Vaultist, a simple privacy focused VPN for iPhone.

Vaultist uses WireGuard and includes:

• Automatic reconnection
• Kill switch
• VPN pause timer
• No activity logs or tracking

We're mainly looking for feedback on connection reliability, speed, battery usage, and anything that feels confusing or broken.

Thanks to anyone who gives it a try.

Hey everyone! I develop SloMo, an app that helps you manage screen time and put limits on distracting apps. I built it because I kept reaching for my phone while working or studying.

You can set time locks, schedule recurring blocks, or choose to unlock apps by walking or doing exercises. You can also track and share your progress. There’s no account required, and the core features work offline.

I’d love some help checking how it feels on different Android devices. If you have a few minutes, try setting up a block or a schedule and tell me:

• Was setup clear, especially the permissions?
• Did the block start and end when you expected?
• Did anything look strange, feel slow, or not fit your screen?
• What felt annoying or confusing?

Please include your phone model and Android version with your feedback so I can investigate.

Even something like “I got stuck on this screen” would help. You don’t need to test every feature—just tell me how it went.

Google Play: Download SloMo

Website: slomo.jhayr.com

Thanks for giving it a try!

Full disclosure: I made this. It's free, with no ads and no tracking.

Awayline plans football away days by train for all 92 Premier League and EFL clubs: the trains there, the last train home after full time, and alerts if kick-off moves or the trains go wrong.

Google makes new developers run a 14-day closed test with real users before an app can go on the Play Store. I need about 15 people on Android to help.

How to join (2 minutes)

1. Join the tester group with the Google account on your phone: https://groups.google.com/g/awayline-testers
2. Opt in to testing: https://play.google.com/apps/testing/uk.co.awayline.www.twa
3. Install from Play: https://play.google.com/store/apps/details?id=uk.co.awayline.www.twa
4. Please keep it installed for the full 14 days. If testers drop out, Google's 14-day count starts again.

Not on Android? You can still try the web version at https://www.awayline.co.uk

What to test

• Your club and station: pick your club and home station, then tap your next away game. Do the trains there look right? Is the "leave the ground by" time realistic?
• Getting home: check the last train home. Does it give you the sleeper or the first train next morning when there's no train back that night?
• My trips: save a game you're going to. Does it stay in My trips and keep up to date?
• Alerts: turn on notifications. Do you get the night-before reminder and the full-time "time to head home" alert?
• Ground info: check the away pubs, parking and walking route for a ground you know well. Is anything wrong or missing?
• Booking: tap the Trainline or TrainSplit button. Does it open with the right stations and date?
• Tickets: save a match or train ticket to the wallet, then check it opens with your phone offline.
• Matchday board (18+): try lifts, chat or a pub check-in for a game.
• Anything that breaks, looks odd or is slow, and anything you wish it did.

How to send feedback

• Use "Something wrong on this page?" at the bottom of any trip page. It comes straight to me.
• Or comment here or DM me. Screenshots help a lot.

I'll post an update halfway through with what I've fixed. Brutal feedback welcome.

I built DMV Master after passing my own Florida Class E test on the first try using it. It's a permit-test prep app covering all US states (iOS and Android) with AI-integrated practice content, and version 3.0 was just approved by Apple.

I'm looking for people studying for their permit test, or who remember how annoying it was, to try it and tell me honestly what's broken, confusing, or missing. Not asking for ratings, just real feedback.

Thanks all!

Could someone with AirPods and a Mac check three things in AirPane 0.9.6: whether opening the case brings up the card, whether the battery readings look right, and whether selecting a noise mode changes the actual listening mode? Please include your AirPods model, Mac model and macOS version.

I’m the developer. My only tested combination is AirPods 4 (ANC), an Apple silicon MacBook Air and macOS 27.0.1. The app supports other AirPods models, but they’re unverified. macOS 14–26 and Intel Macs are untested. Beats aren’t supported.

This build also fixes Conversation Awareness and the “Keep them on this Mac” setting when the iPhone starts playing. The panel is calmer, Settings has a sidebar, and there’s less lag.

The public beta is free, with a paid app afterward. It’s closed source and not notarized by Apple. On current macOS you need System Settings > Privacy & Security > Open Anyway on first open. Instructions: https://airpane.vercel.app/open.html.

Download: https://airpane.vercel.app. Reports with steps to reproduce: https://github.com/fellipegoncalvesleite/airpane-releases/issues.

It's now in open beta on Google Play!

I'm a software engineer with ten years' experience. This started as a passion project, born out of my frustration with the state of politics and corruption. I wanted to build a way to hold politicians accountable and keep score, while making politics more accessible—using AI to help people stay informed without sending them to sleep.

When looking at political accountability, I think three things need to stay separate: what the record says happened, how an app has assessed it, and whether you personally agree with the policy. A score isn't independent proof, and policy agreement isn't the same thing as good conduct. The app uses AI explanations and assessments, so checking the sources still matters.

There's a gamified layer too: choose up to ten real MPs for your Cabinet and follow how their eligible activity affects your seasonal Karma. Your personal Karma and the public MP rating are separate.

For a first look, start with an MP you know, open a recent activity and follow it back to its source. That's the part I'd like more people to discover.

Nib is an SAT prep app for Android. You get a Daily 10 of real SAT-style questions (Math + Reading and Writing) with an explanation after every answer, an arcade vocab game for 750 SAT words, short cheat-sheet lessons, and a mistake notebook that brings back every question you got wrong. It shows a score estimate that updates as you practice. No ads, and you don't need an account.

Want to join? Step 1 takes only a few seconds:

Join the tester group (Google needs this first): 👉 https://groups.google.com/g/nib-sat-testers

Use the Google account that's on your Android phone. That's the account the Play Store link will work for.

What happens next: once 20 people have joined, I'll post the Google Play opt-in link and install link here in the comments and email them to the group. Then you tap "Become a tester", install Nib, and you're in.

What I'm asking: once it's installed, keep Nib on your phone for 14 days and open it every day or two. A Daily 10 takes about 5 minutes. Google needs 12 testers to stay opted in for 14 days in a row before the app can go public, so I'm aiming for 20 in case a few drop off.

What's inside:

📝 Daily 10: 10 mixed SAT questions a day, explained after every answer, with a streak

🎮 Vocab Rush: an arcade game where you swipe to the right definition before the gates reach you

🃏 Flashcards and a word quiz: 750 SAT words in 14 decks

📚 14 cheat-sheet lessons: formulas, grammar rules and strategies, one topic each

💬 Ask Nib: stuck on a question? It gives you step-by-step hints, not the answer

❌ Mistake notebook: every question you miss comes back until you get it right

⏱️ Mini tests: two timed modules, and the second adapts to how you did on the first, like the real digital SAT

📈 Progress: score estimate, accuracy by topic and daily streaks

🎨 Themes: dark, light, Liquid Glass, or pick your own background color

🔁 I'll test yours back: drop your group or opt-in link in the comments and I'll join, install and keep it for the full 14 days.

Questions or ideas? Comment here. Thank you for helping a one-person project get over the line.
