This update brings the app in line with modern Android Development Toolchains.
The app has been re-written in Kotlin and updated to use Jetpack Compose. As a result, the app now responds to the user theming introduced in Android 12 (Material You) and in the sprit of Material You, as with all my apps, a 'Themed Icon' has been provided too so if you add the app to your home screen then it will fit in with the rest of the app icons. In fact, I should probably step back a bit: the previous version didn't have an icon at all, so an icon has been added to this release too.
Hopefully this release future proofs the app, and won't need to be updated again for a while. If there are any problems, please raise an issue in GitHub and I'll investigate it.
Cheers, and enjoy
