What and why
I wanted to have a straightforward, free multi-timer application that does not contain ads.
I also wanted to extend the app with new features over time if I needed to rather than look up some app on the Google Play Store that matches my needs.
How
To implement the application, I used Kotlin and Android Jetpack components.
Problems
On some Huawei devices, the application still gets killed if it runs in the background with a device screen turned off, although I used known workarounds for this issue.
Results
The application is released and available in the Google Play store
The application supports several languages: English, Japanese, Russian, Arabic.
