Made a small iOS app to see my charging curves and real cost per charge, looking for feedback
I've had my Model Y for a while and kept getting annoyed that the Tesla app doesn't really show what happened during a charge. I wanted to see the actual curve, how fast it charged at what percentage, and what each session cost me at home vs at Superchargers. So I ended up building it myself.
It's called Tescar. It shows the charge curve for every session (power, battery % and battery temperature), the cost based on your own electricity price, and a drive log with route, consumption and elevation. There's also a stats page for monthly kWh, km and spend, and it tracks how much battery you lose while parked. While charging or driving it puts a Live Activity on the lock screen.
One thing I cared about was not draining the battery. It uses Tesla's official Fleet Telemetry, so the car sends data on its own and the app never wakes it up. Login goes through Tesla's own sign-in page, so I never see your password, and you can remove access from your Tesla account whenever you want.
It's a subscription because the server costs money, but there's a 14-day free trial if anyone wants to try it:

It's just me working on it, so honest feedback is very welcome. What would you want to see in something like this?
