I started using an app called aCar back when I used Android, then that app was purchased and the lifetime users were forced to subscribe. The name was changed to Fuelly and the new owner abandoned it 4+ years ago.

I have looked at a couple on iOS and they either are barely functional (only tracking fuel ups) or very extensive app permissions are used.

I am looking for something that will track multiple cars, ideally across multiple devices so my wife and daughter can track theirs too. Fuel, maintenance, part numbers, etc.
