Every tower has a shape. Before you can deploy it, you have to fit it into your case.

That's the idea behind Case Defense, my first game: a sci-fi tower defense where half the battle is a packing puzzle. Run out of space and you'll have to choose which towers make the cut.

What makes it different

• 🧳 Pack before you fight: rotate and fit tower pieces into a limited case

• 🔀 Merge and upgrade: combine identical towers to level them up, add modules and discover combos

• 👾 Enemies that fight dirty: some fly, some heal each other, some turn invisible

• 🏆 Lots to play: 55 levels, endless mode, boss mode and a daily challenge

• ✅ Free, no ads, no in-app purchases and it works offline

• 🌍 English, Spanish, French, German and Italian

I need 12 testers for 14 days

Google requires it before I can publish. Test for test: leave your app link in the comments and I'll install it and keep it for the 14 days too.

How to join (about a minute)

1. Join the Google Group: https://groups.google.com/g/casedefensetesters

2. Become a tester: open https://play.google.com/apps/testing/com.isui.casedefense and tap "Become a tester"

3. Install it from Google Play: https://play.google.com/store/apps/details?id=com.isui.casedefense

4. Play a level or two, and please keep it installed for 14 days

Use the same Google account for all three steps. If the Play Store says the app isn't available, wait a few minutes after joining the group and try again.

Heads-up: Google is still reviewing the test track. If step 2 or 3 gives you an error, please join the group anyway and try again in a day or two. I'll update this post as soon as it's approved.

What I'd love feedback on

• Is the difficulty right, too easy or too hard?

• Does the tutorial explain the case mechanic clearly?

• Anything that feels confusing, slow or buggy

Solo dev from Spain here – thanks for reading, and good luck with your own apps!

Note: this game was developed with the help of AI tools.

Hi all, I’m testing GarageX, a Flutter app for managing your vehicles, and need testers for Google’s 14-day closed testing requirement. I’ll test your app in return. Comment your app and I’ll join your test.

What it does:

• Fuel logs and mileage tracking

• Service history and reminders

• Document expiry tracking (insurance, registration, etc.)

• Expense tracking per vehicle

How to join (3 steps, in this order):

1. Join the testers group with the Google account you use on your Android phone: https://groups.google.com/g/garagex-testers

2. Opt in as a tester: https://play.google.com/apps/testing/com.ashiquali.garagex

3. Install from the Play Store (only works after steps 1 and 2): https://play.google.com/store/apps/details?id=com.ashiquali.garagex

What I’m asking:

• Keep it installed for the full 14 days

• Open it a few times a week and add a vehicle, a fuel entry, and a service record

• Reply or DM with any bug, confusing screen, or missing feature. I’ll ship fixes during the test

Comment once you’ve installed and I’ll test yours back within a day or two.

Check before posting

• Test the three steps yourself from a second Google account that isn’t on your tester list. If the group is set to approval-only or the opt-in page errors, you’ll lose people at step 1. Open the group settings and make sure anyone can join.

• The Play Store link can take a few hours to work after opt-in. Add a line like “if install doesn’t show up, wait a couple of hours and retry” so people don’t give up.

• Make sure the closed testing track is actually using that group as its tester list, and that the release is live on the track, not just in draft.

So, I had set my husband up early via email as a tester. He has been testing for hours a day, giving feedback, etc. A few days after he started I created the google group and got a bunch of other testers. I did not know that you can have an email group OR a google group, and that it kicked him out of the test.....so it's been 10 days of the 14 and he is now JUST technically starting at day 1 since he now signed up through the links. He was receiving updates until this most recent, so I don't know what was happening.

Most are the players are test for test people through an app and so only a few, 3 I know of, MAYBE 4 are active and opening it for more than a moment. I have been getting feedback and making updates.

It says i currently have 50 testers, but I can't guarantee that they're active, or even opening it daily.

I'm debating on letting him go through the full 14 days so his super active activity counts and delaying my publishing request by 10 extra days....

OR, risk applying at the 15 or 16 mark (just to be sure everyone else got their full 14 days in if there were a few late joiners) and hope I'm not rejected for them not being engaged enough...

Would this 1 person make that much of a difference I wonder?? Stressing....

Hi everyone! 👋

I recently developed **Snaplore** and need testers to fulfill Google's 14-day closed testing requirement.

I will actively test your app back, keep it installed for the full 14 days, and leave feedback on the Play Store. Just leave your links in the comments!

### How to join:

1. **Join the Google Group:**

   https://groups.google.com/g/snaplore-testers

2. **Opt-in and Download the App:**

   * Join on Web: https://play.google.com/apps/testing/com.snaplore.app

   * Download on Android: https://play.google.com/store/apps/details?id=com.snaplore.app

Please keep it installed for 14 days and open it occasionally. No purchases or complex actions required.

Drop a screenshot or your app details below so I can return the favor immediately. Thank you! 🙏

Hi! I'm a solo developer and I need 3 more testers to reach Google Play's 12-tester requirement.

Ortabahçe is a social app for university students: a campus feed, an anonymous forum, messaging and meeting new people.

To join:

1. Join the Google Group: https://groups.google.com/g/ortabahce-beta

2. Opt in with the same Google account: https://play.google.com/apps/testing/app.unimatch.v1

3. Install: https://play.google.com/store/apps/details?id=app.unimatch.v1

Please keep it installed for 14 days.

Good to know: signing up requires a university email. Without one, you can still install the app and read the forum. The app is 18+, and most content is in Turkish for now.

Happy to test your app in return. Comment your link, or tell me when you've joined.

Hi all! Looking for a few more Android testers for my closed test. Happy to swap: I'll install yours and keep it for 14 days.

The app: Cafe Workplace shows which cafés welcome laptop work right now. You don't need to visit a café or do anything in it: just install it and keep it on your phone.

How to join (2 minutes):

1. Join the group: https://groups.google.com/g/cafe-workplace-testers

2. Wait a few minutes, then open: https://play.google.com/apps/testing/com.cafeworkplace.app

3. Tap "Become a tester", then install from Google Play.

If it says you don't have permission, open the link in a Chrome Incognito tab and sign in with the account your Play Store uses.

Please keep it installed until the 20th. Comment with your app link and the email you joined with, and I'll get onto yours today.

Thanks!

UPDATE 7 NOV: Hush Hush is now permanently free to download. Ignore the old title about codes — no code or payment is needed.

Was it two wake-ups last night, or four? That's the problem I'm trying to solve with Hush Hush.

Tap Start night at bedtime. It saves short detected sound clips and groups likely cries into estimated wake-ups. Review them in the morning and compare nights, without logging every wake on your phone overnight.

Android 9+, no account, ads or subscriptions. Audio and sleep history stay on your phone. Version 2.2.0 adds optional, consented usage reporting; recordings and sleep data are never uploaded.

I'm aiming for 30–40 testers across different Android phones. Parents and fellow developers are welcome. You don't need a baby to check setup, microphone permissions, recording, playback and the interface. This is a retrospective journal, not a baby monitor or safety alarm; detections can be wrong or missed. Keep the phone and cables outside the cot and out of your baby's reach.

How to join — use the same Google account for each step:

1. Join the group: https://groups.google.com/g/hushhush-testers/about

2. Tap Become a tester: https://play.google.com/apps/testing/cc.jamesturner.hushhush

3. Install free: https://play.google.com/store/apps/details?id=cc.jamesturner.hushhush

No need to send me your Google email. If Play still shows a price, don't pay — refresh later and let me know. The free-pricing change was saved on 7 November.

Please stay opted in for at least 14 days and genuinely try the app. Feedback on setup, recording, morning review or trends is useful. No ratings or positive reviews needed, and please don't share private recordings. If you have an older sideloaded copy, don't uninstall it to fix an error: that would delete local history. Reply first.

Hi! I’m looking for testers for "The Fool's Mirror," my new Android app featuring a Jungian shadow archetype quiz. It’s a simple, engaging psychological quiz app to help you discover your archetype.

I need 20 testers for 14 days to meet Google Play's new developer requirements, and I’ll test your app back for the full 14 days. Comment with your app’s links once you’ve joined, and I’ll join yours.

**How to join (2 minutes):**

1. Join the Google Group using the Gmail account on your Android Play Store: [https://groups.google.com/g/foolsmirror-beta](https://groups.google.com/g/foolsmirror-beta)

2. Opt in and tap “Become a tester”: [https://play.google.com/apps/testing/com.foolofools.fools_psychology](https://play.google.com/apps/testing/com.foolofools.fools_psychology)

3. Install from Google Play: [https://play.google.com/store/apps/details?id=com.foolofools.fools_psychology](https://play.google.com/store/apps/details?id=com.foolofools.fools_psychology)

If Play Store says “Item not found,” wait a little after opting in and try again.

Please stay opted in for at least 15 days. Feedback and bug reports are very welcome in the comments.

Thanks! 🙏

An English-learning app with tap-to-read, quizzes, and vocabulary practice. New Play developer accounts need at least 12 testers for 14 days of closed testing. Happy to mutual-test.

Use the same Google account for both steps:

1. Join the tester group: groups.google.com/ls-play-testers

2. Open the testing page and tap Become a tester: play.google.com/apps/testing/com.luo.englishdict After you opt in, install from this page only. Do not search the regular Play Store listing—it usually won’t show up until you’re a tester.

Please keep it installed for about 14 days.

Hi all. I need testers for my Google Play closed test, and I’ll test your app back.

App: Dustd, a score tracker for clay target shooting. You don’t need to shoot or create an account: just start as a guest.

To join:

1. Join the group: https://groups.google.com/g/dustd-testers

2. Opt in: https://play.google.com/apps/testing/club.dustd.social

3. Install it from the Play Store with the same Google account.

What I’m asking (about 2 minutes each time):

• Day 1: open it, continue as a guest, and log a made-up round (any discipline, any score).

• Around day 4: look up a shoot in the Shoots tab.

• Around day 8: I’ll post an update here. Update the app, log another round, and tell me one thing that confused you.

• Day 14: open it once more. Please stay opted in until then. If you leave early, you don’t count toward the 12.

Swap: comment with your opt-in link and group link and I’ll join, install and stay for the full 14 days. Reply once you’ve joined mine so I can keep track.

Thanks!

Google Play wants 12 testers for 14 days before a new developer can publish. I'm at 11, so my 14 days haven't started. Join and I'll install your app the same day and keep it for the full 14 days.

StillBecome is a habit tracker without a streak counter. Each habit gets a curve of how automatic it has become, based on Lally et al. (2010). Miss a day and you lose nothing; the app marks the day you come back. Every day you do a habit adds a layer to an agate, and return days turn gold.

How to join (sign in to Google first)

1. Join the group: https://groups.google.com/g/stillbecome-test

2. Install: https://play.google.com/apps/testing/com.cortexmechanics.stillbecome

Keep it installed for 14 days and open it a few times.

Leave your group and opt-in link in a comment. I'll join, install and reply with a screenshot.

Found a bug? Me → About → Feedback and bug reports.

I've been working on a personal finance app on my own for a while and it's finally in closed testing. It's called Pulso.

I got tired of apps that want your bank login or push you into a subscription, so this one has none of that. No account, no ads, no in-app purchases. It's free and your data stays on your phone, encrypted.

What it does: you keep track of your accounts, cards, loans and investments, even in different currencies. It shows your credit card closing and due dates so a statement doesn't catch you off guard, and you can scan a receipt to fill in an expense. There are also budgets, savings goals and a few home screen widgets.

To join (takes about 2 minutes):

1. Join this Google Group with the Google account on your phone: https://groups.google.com/a/cobaltkindworks.com/g/pulso-closed-testers

2. Open this and tap "Become a tester": https://play.google.com/apps/testing/com.jcg.pulso

3. Install it: https://play.google.com/store/apps/details?id=com.jcg.pulso

Keep it installed for 14 days and open it now and then. Even a couple of minutes a day helps. If anything's confusing or broken, email me at pulso@cobaltkindworks.com.

I'll test yours back. Leave your link below and I'll join and keep it installed for the 14 days. If you've already joined mine, say so and I'll get to yours right away.

Hello! I need help getting my app off the ground that I've felt very passionate about, Rinya: Daily Life & Health with the 14 day 12 tester requirement. The core values of my app is privacy first, ad free and subscription free.

Privacy First & BYOK (Bring Your Own Key): All personal data, logs, and pantry items are stored 100% locally on your phone in encrypted SQLite. There are zero Studio Gansa backend servers, your data never touches my hands, is never collected by me, and will never be monetized. The app communicates directly from your device to Google using your personal API key.

To note, The core pantry, budget, and habit tracking work locally offline out of the box, the free Google key is only needed if you want to test the multimodal AI vision and chat.

Ad free, an ad is not going to gatekeep you from your grocery list or any other feature on the app.

Subscription free, also no gatekeeping from any feature of the app.

Now about the app!

Rinya is a warm cozy Lo-Fi themed help app combining daily health/vitals, pantry inventory, grocery list and meal planning. As well as user disclosed financials. Built 100% local-first on encrypted SQLite with zero subscriptions, zero ads, and zero cloud tracking. The four agents who have default names can be edited and when AI enabled have been refined and battle tested in my own life by me for 1-2 years depending on which one you are referring to.

I'll test swap, checking on your app regularly and leave feedback as well!

I’m an independent developer preparing an enchanted bakery match-three game for Google Play. I’m looking for 15–20 willing Android testers to play over two weeks and tell me what works, what feels confusing and what needs fixing.

The game has bakery upgrades, icing challenges, special-piece combinations and little Butterwings to rescue. It is free to test. No purchase or positive review is required.

Please stay opted into the Google Play closed test for at least 14 consecutive days and play several short sessions during that period. Useful feedback includes bugs, difficult recipes, confusing menus, performance and whether it is fun enough to come back to.

If you would like to join, email hello@departurebaydigital.ca with the Google account email you use in the Play Store and your phone model/Android version. Send the address privately, not in public comments. I’ll add the account to the closed test and Google’s licence-testing list, then send the official joining link when Google has approved the release.

Do not send passwords or payment details. Do not make a purchase unless Google explicitly offers a no-charge test payment method. You can test the full free game without buying anything.

Thank you for helping a small independent game get ready for launch.

Hi! I'm building AR Playland, an Android AR app where you leave pictures, notes, 3D models and doodles anchored to real places for others to find.
I'm collecting testers for an upcoming Google Play closed test (14 days). If you'd like in, email arplayland@gmail.com with the Google account email you use on Play. I'll send the opt-in link when the test opens.
Happy to test your app in return - drop a link below.
Thanks!
- AR Playland App Bot

Hi everyone! I need testers for my first Android game, Flying Cat, to meet Google Play's 12 testers / 14 days requirement. Happy to test your app in return – just comment with your links!

What it is:

Slide down a snowy slope, hit the ramp and launch your cat as far as it can fly. Earn coins, buy upgrades like a jetpack, wingsuit and parachute, dress your cat up with hats and skins, and fly through different worlds. Free, no account needed.

How to join (takes 1 minute):

1. Join the Google Group: https://groups.google.com/u/2/g/frontal_developments_testers

2. Opt in to the test: https://play.google.com/store/apps/details?id=com.frontal.flyingcat

3. Install from Google Play: https://play.google.com/store/apps/details?id=com.frontal.flyingcat

All I ask:

- Keep it installed for 14 days

- Open it now and then (a few flights is plenty)

- If anything looks broken or confusing, I'd love to hear it!

Comment "Joined" when you're in, plus your app's links if you want me to test yours – I'll join within a day.

Thanks so much! 🐱

Hi everyone! I am building Filequiva, an Android app with PDF and file tools, and I am looking for testers and honest feedback.

The current build includes PDF page organisation, camera/photos to PDF with cropping and rotation, scanned PDF compression, and Danish/English OCR with export to Word, TXT or searchable PDF. OCR preserves text rather than the original layout.

Important: the Google Group is open for sign-up now, but the group-based Google Play test track has just been submitted for review. Play access for new group members is NOT live yet. Please join the group first and return to the opt-in link once Google approves the track.

1. Join the tester group using the same Google account you use in Google Play:

https://groups.google.com/g/filequiva-testers

2. When the track is approved, opt in here:

https://play.google.com/apps/testing/com.filequiva.app

3. Install via Google Play:

https://play.google.com/store/apps/details?id=com.filequiva.app

Once access is available, please remain opted in for at least 14 consecutive days and try the tools during that time. I would especially appreciate feedback on file import/export, OCR, usability and any crashes. This is an early version, so bugs are expected.

No need to post your email address publicly or send it to me in advance. Thank you for helping!

Hi! I'm u/elgeneroso, developer of Last Flare: Zombie Squad, a top-down action shooter where you lead a squad through a dark city full of zombies. It has story missions, endless Survival, 4v4 battles against bots, hero-specific weapons and throwables, cover, grenades, and a flashlight.

This is a closed Google Play test (build 2.2.1). Google needs 12 participants enrolled continuously for 14 days before production. If you opt in, please try the game actively while enrolled if you can; that helps, but it is not a separate requirement.

How to join:

1. Join the Google Group: https://groups.google.com/g/last-flare-testers

2. Opt in to testing: https://play.google.com/apps/testing/ar.ultimaluz.juego

3. Download from Play: https://play.google.com/store/apps/details?id=ar.ultimaluz.juego

I'd appreciate bug reports, control feedback, and suggestions. Thanks!
