Hi r/TestMyApp! I’m looking for volunteers to test Sonata Engine Explorer, a free, independent Android app from WrenchHarbor Studio. Explore an interactive 3D vehicle, select components and browse reference summaries. The model and reference coverage are approximate and incomplete.

I’d value feedback from ordinary phones: does pinch/drag feel natural, can you select small parts, are labels readable, and does loading work reliably? Foldable feedback is welcome too. Please keep testing to the app; no vehicle work is needed.

Version 1.4.4 is available through Google Play’s closed testing. It requires Android 8+ and WebGL2 support in Android System WebView; Play currently estimates a 13.2 MB download. Production access is still pending.

To volunteer, privately email [wrenchharborstudio.support@gmail.com](mailto:wrenchharborstudio.support@gmail.com) with the Google Play account address you consent to add to the tester list. Keep email addresses out of public comments. After I add you, use the official opt-in link and install through Google Play:

https://play.google.com/apps/testing/com.sonata.engineexplorer

Google requires at least 12 testers opted in for 14 consecutive days; I’m aiming for 18–20 volunteers for a buffer. If you can stay opted in and try the app a few times, honest bug reports would help. There’s no fixed daily time quota.

Thanks,

Hi! Natsumar is a small free wallpaper app I made: around 185 summer wallpapers in city pop, anime and other styles, a home-screen widget and favorites. No ads, no account needed. The art is AI-assisted, hand-picked and edited by me.

Google needs 12 testers for 14 days before I can open it to everyone. Two links for joining: https://groups.google.com/g/natsumar-beta and then become a tester https://play.google.com/apps/testing/com.inkoherence.natsumar

Leave your app's link in the comments and I'll install it and keep it for the full 14 days.
Please, try to use the app (not only install it):

Feedback is very welcome!
Thank you!

Hi everyone! I’ve been working on a small iOS game called Last Button and I’m looking for a few people to test it on TestFlight. 

It’s a one-tap arcade game where you release a button at the right moment and try to catch the next pin.

If anyone wants to test it, I’ll drop the TestFlight link below. Any feedback is really appreciated!

Thanks in advance to anyone who gives it a try!

Hi! I need testers for my closed test. I'll test your app back for the full 14 days — just comment your links.

PasteInvoice turns any client message (WhatsApp, email, notes) into a professional invoice PDF in seconds. No account, no ads.

How to join (2 steps):

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

2. Become a tester and install: https://play.google.com/store/apps/details?id=com.ironforge.pasteinvoice

Please keep it installed for 14 days and create one invoice (tap "Paste to invoice" → an example → Create). Takes 10 seconds.

Comment "joined" + your app's group/opt-in links and I'll join yours today. ✅ I check comments daily.

Hey everyone,

I'm a solo dev and built Awaken-Fitness, a strength-training tracker with RPG elements (levels, quests, a league system). It's already live on the iOS App Store, and now I want to get it onto Android too.

Google requires at least 12 people to have the app installed for 14 straight days before I'm allowed to release it publicly — it's basically just a formality, you don't need to actively use it (though feedback is always welcome if you feel like it!).

If you've got an Android phone and can spare 2 minutes + 14 days of storage space, I'd really appreciate it. Just drop a comment or DM me (German or English both fine) and I'll send you the link.

Thanks a lot! 🙏

I’ve built a site that finds part-time jobs near you, writes cover notes, and fills in application forms with a Chrome extension, so its faster and easier for you. Only works on pc for now, and im not sure how well it works for every job, so looking for testers, theres also a auto complete function where the extension completes as soon as you enter the application, but doesnt submit so you can make sure its all right. It shouldn't take too long, 30 mins ish to see how it works etc

DM me to get a tester code for the website Firstshift.me

Hi everyone, my names Olivia and I’ve been developing an app for pet care providers. I’m a dog walker myself and noticed there was nothing out there for us. I’m close to announcing the launch but just want to make sure it’s all working and I haven’t missed anything prior. You don’t have to be a dog walker to test it, even if you just want to have a scroll through for me. It’s on the App Store as PetCare Suite but if you’d like to have full access for free please leave your email or message me so I can add you to the TestFlight group. Thank you all so much!

Hi, I’m Joost, the founder of ColorBestie. I work on the product myself and would like feedback from people who enjoy coloring on paper.

ColorBestie lets you upload a sketch or coloring page, generate an AI color preview, and use marker color suggestions to plan a coloring session. You can save previews for later inspiration. It is freemium; the website also has free printable coloring pages, marker tools and printable swatch charts. It is available on Android, iOS and the web.

If you try it, I’d especially like to know:

1. Is it clear what to do after opening the app or website?

2. Can you find the upload and color-preview steps without getting stuck? Please use a page you own or have permission to upload.

3. Do the preview and marker suggestions help you decide which colors to use on paper, or is anything confusing?

4. Is the distinction between free and paid features clear before you make a choice?

iOS: https://apps.apple.com/app/id6761053389

Feedback here in the comments is welcome, including anything that did not work and the device/browser you used. Please don’t purchase anything just to test it.
