The app was on Google Play in the past, but my developer account has been deleted because I didn't want to send my ID to Google.
At the time of removal (2025-05-21), the app had been installed on 1.7k devices and had rating of 4.8 stars (21 reviews, 6 comments).
To download the app, use one of the options below:
You need to have Obtainium installed. Then, click the following:
Download the APK file from Releases → Assets → app-release.apk.
To install it, "Install apps from unknown/external sources" option has to be enabled in your Android. This option should be found somewhere in settings. You can try:
"Settings → Apps & notifications → Special app access → Install unknown apps"
"Settings → Security → Unknown sources"
Open the downloaded APK file and you should be able to install it. You might see a "Blocked by Play Protect" message, because I'm not a verified developer and the app is not being installed from Google Play.
Clone this repository and import it into Android Studio.
See the Build and Run menu to run the app, build it or generate signed APK.
