Battery you can trust
Remaining energy, usable capacity and state of health, calibrated against the car's own battery management data — not a rough range estimate.
TesInfo is an iPhone companion app that turns your car's telemetry into accurate battery health, real trip energy and cost, and live driving insights.
Private beta on TestFlight · App Store release coming
Remaining energy, usable capacity and state of health, calibrated against the car's own battery management data — not a rough range estimate.
Trips and charging sessions are logged automatically in the background, with route maps, real kWh, Wh/km efficiency and cost.
Built on Tesla's official Fleet Telemetry streaming. Data is pushed from the car, so we never keep it awake just to check on it.
Where did the energy go overnight? Is this hill cheaper at 50 or 70 km/h? TesInfo is built to answer the questions owners actually ask.
