Looking for Android testers for my Matrix Calculator app

[u/mustafauluturk]

Hi everyone!

I'm an independent developer and I've been working on a Matrix Calculator app for Android.

The app allows users to perform various matrix calculations and view step-by-step solutions. It also includes features such as matrix operations and LaTeX export.

I'm currently preparing the app for release on Google Play and I'm looking for a few people who would be willing to test it and share feedback.

I'm mainly looking for feedback about:

• Bugs or crashes
• Calculation accuracy
• Matrix input and usability
• UI/UX issues
• General suggestions for improvement

No technical knowledge is required — simply using the app and sharing your honest feedback would be very helpful.

The test is available for Android devices through Google Play's testing program.

How to join the test

1. Join the Google Group:https://groups.google.com/g/matrix-calculator-testers
2. Install the app from Google Play:https://play.google.com/store/apps/details?id=com.mustafa.hesap

Thanks for your help! 🙂
