Consider better telemetry and feedback

[wonrax]

I literally have no idea how the app is being used, apart from statistics on Google Play Console that tells me how many active users there are monthly or daily (DAU barely works), how many people have installed and uninstalled the app and some other device hardware and software metrics.

Also no one has filed an issue on GitHub. Does that mean my app has no bugs? But the dashboard shows 1.11% User-perceived crash rate. So maybe a better crash report could help?

I'm considering Firebase Analytics and Firebase Crashlytics since they're popular and completely free of charge.
