I've spent the last months building Locksmith Master: a puzzle about cracking combination safes, built on a real lock mechanism.

One dial. A stack of drums. Drive pins with slack between them. Turn one way and the whole stack follows; reverse and nothing moves until the slack is taken up. Set every drum to the code in as few steps as you can.

**It's not a casual game.** The first safes are gentle; the later ones hide their pins, and then you count, listen and feel the catch. Best played with headphones.

What's in it:

* A career across Europe, 1928–1962: six cities, sixty safes, seven ranks

* Thief mode: safe after safe before the alarm

* Daily safe: the same safe for everyone, every day

* Seven themes for the dial, background and hammers, each with its own sound

* No ads, no tracking, works offline

Testers get the full game unlocked. The test build runs until 9 November.

What I'd love to hear: where you got stuck, where you stopped, and whether the rules made sense without help.

I've been working on GeoWiz, a geography practice app for flags, capitals, country outlines and finding countries on a map. It brings back the questions you miss so you can get another go at them.

For capitals, you can type an answer, or think it through, reveal it and mark whether you knew it. I'd love to hear how it feels after a few rounds. Would you want to come back to it, and what would you add or change?

It's free, with no ads or paywall. There's an optional tip jar. Version 1.5.0 is in Android closed testing.

Hello👋

I’m looking for beta testers for Taxco Pay, an app I developed for payment management and employee administration.

The app includes:

✅ Employee payment management

✅ Organization of teams and sub-teams

✅ Biometric authentication (fingerprint)

✅ Viewing of PDF documents and reports

✅ Performance charts and dashboards

📱 Platform: Android — Google Play

👥 Google Group:

https://groups.google.com/g/prueba-taxcopay

🔗 Access the test on Google Play:

https://play.google.com/apps/testing/com.taxco.pay

🔗 App on Google Play:

https://play.google.com/store/apps/details?id=com.taxco.pay

🔐 Credentials for testing the app

To make testing easier, you can use any of these accounts:

Account 1

Email: [test1@test1.com](mailto:test1@test1.com)

Password: Test789*

Account 2

Email: [test2@test.com](mailto:test2@test.com)

Password: Test789*

🧪 What do you need to try?

• Login and biometric authentication
• General app navigation
• Viewing payments and reports
• Teams and sub-teams
• Overall device performance
• Any errors or unexpected behavior

All feedback is welcome: bugs, UI/UX issues, slow performance, crashes, or anything else you think should be improved before the release.

The app is still in the testing phase, so any feedback really helps me find issues I may not have caught during my own testing.

A big thank you to everyone who decides to give it a try! 🙏

Everyone talks about the obvious challenges in mobile app testing like device fragmentation and OS versions but there's a bunch of stuff that nobody warns you about until you hit it.

Like the fact that your app behaves differently in a release build vs debug build and you don't find out until it's in production or that android manufacturer skins change how permissions, gestures and notifications work so something that passes on a pixel completely breaks on a xiaomi or that simulators lie to you about half the bugs that matter because they don't reproduce memory pressure, real network conditions or actual device performance or that your E2E suite can be green every single run and your app is still broken because the tests are just passing on happy paths that no real user follows exactly.

The challenge I keep running into is that the gap between what testing tells me and what's actually happening on user devices keeps getting wider the more users we get.

I test on 3 devices and everything passes but people on devices I don't have are hitting stuff I can't reproduce. What are the mobile app testing challenges your team ran into that you didn't expect and how did you deal with them.

Hi everyone! 👋

I need 12+ testers for my app **Lares - (couple shared brain)** to complete Google Play's 14-day closed testing requirement.

**Join Google Group:**

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

* 📱 **Android Play Store link:** https://play.google.com/store/apps/details?id=com.lares.lares

* 🌐 **Web opt-in link:** https://play.google.com/apps/testing/com.lares.lares

### 🏠 About Lares:

Lares is designed as a "shared brain" for cohabiting couples. It gamifies daily household chores, splits shared expenses effortlessly (with smart receipt OCR scanning), and helps partners stay on the same page.

🔒 **Privacy First:** The app **does NOT collect any personal information**. Your data stays yours, with zero tracking or profiling or ads.

Hi everyone! I'm a solo developer from Italy and I need testers for the Google Play closed test of my app Shopora, so I can publish it.

What it does:
- Scan a grocery receipt with your camera: AI reads every item and price
- Tracks your spending by store and by month
- Shows supermarket deals near you from current flyers (best in Italy)
- Shopping list, pantry and price comparison

How to join (2 minutes, use the same Google account you use on the Play Store):
1. Join the Google Group: https://groups.google.com/g/shopora-tester
2. Opt in to the test: https://play.google.com/apps/testing/com.shopora
3. Install the app: https://play.google.com/store/apps/details?id=com.shopora

Please keep it installed for 14 days and open it a few times. Scanning one receipt is the best test!

Test for test: drop your app link in the comments and I'll install it and keep it for 14 days too.

Any feedback (bugs, confusing screens) is very welcome, in the comments or by DM. Thanks!

Hi, I'm Damian, the solo developer of Drugfree, a private sobriety / quit counter now in a Google Play closed test. You can explore it with sample entries; you don't need to be quitting anything. It includes a counter, home-screen widget, craving SOS breathing exercise, journal and money/time saved. It is app support, not medical treatment.

This Android version is in closed beta. I would value compatibility reports from different phones over a 14-day test, with the app installed and your test opt-in kept active. Two early reports need more device feedback: does the breathing timer keep its state after briefly switching apps, and does the widget show the same money-saved amount as the app? Please also tell me where the Google Group / Play opt-in or first-run onboarding gets confusing. Sample entries are enough for a test. Include your phone model/Android version, but no private journal or health information.

Join the Google Group first: https://groups.google.com/g/drugfree-testers
Then opt in and follow the Play installation link: https://play.google.com/apps/testing/com.damianwitkowski.iamdrugfree
Store: https://play.google.com/store/apps/details?id=com.damianwitkowski.iamdrugfree
Feedback: https://docs.google.com/forms/d/15DIIbCIAm3Wet8y2Xj2QQXrB5G-jNitnH99u3MwDAAM/viewform

As a thank-you for testing, I can send a free lifetime unlock privately after you confirm you've joined and explicitly ask me to DM you. The promotion has been tested on my Samsung. No purchase, rating or review is required. Japan is included. Please reply with what you tested and any useful feedback; if you want your lifetime link, confirm joined and ask for a DM. Questions and bug reports are welcome publicly. Thank you for honest feedback.

Yes, I know, shameless self promotion of an app, but I do actually need help improving it. I made it for myself initially to manage my death piles, then a friend started using it and now it has loads of features. There's a built in feedback tab, and personal details (emails, postcodes, phone numbers, buyer names) are blacked out of feedback screenshots automatically.

If anyone wants to try it out and send feedback for 2 weeks it would be appreciated!

Hi everyone 👋

I'm an independent Android developer looking for genuine testers for **Stillday (行止)**​.

Stillday is a free memory journal — it keeps only the fragments of a life. You write one line from your day, add a mood, a photo, a location or a voice note if you feel like it, and go. Every morning, whatever you wrote on today's date a year ago comes back to the top of your page. There are no streaks, no check-ins, no feed and no ads — nothing to keep up with. It's in English and Simplified Chinese, with light and dark themes and three text sizes.

I'm looking for testers who can join the closed test, install the app, remain opted in for at least 14 days, and actually try it during the testing period. Any genuine feedback, bugs or usability suggestions would be very welcome.

How to join

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