There will be of course errors and bugs as i haven´t had opportunities to test all than mostly on my own Volvo. So when you send that 850log.txt file to me via email (in settings has one click solution to send via email) i can maybe do something to fix it or at least let you know can i and why..

Will be updated based on feedback.
Thanks for your support! I hope this will be useful and i will make it even more useful by time!

I don´t take any responsibility what this app can cause by using it or while using it.
I don´t warrant any things this app says. Many are just best guesses by looking at them and will be fixed as noted.
App doesn't have any tracking of users (it asks location permission because of bluetooth permissions.. sorry*) only what Google Play Store does itself(counting etc).

*To access the hardware identifiers of nearby external devices via Bluetooth -- scans, your app must now have the ACCESS_FINE_LOCATION or ACCESS_COARSE_LOCATION permissions

*To have Wifi support needed to have next permissions; CHANGE_WIFI_STATE and android.permission.INTERNET.
