From live telemetry to long-term battery trends — every detail of your car, measured and made legible.
Battery level, range, location, climate and tyre pressure — pulled straight from your Tesla via the official Fleet API and always current.
Every session logged with cost breakdowns, energy added, efficiency curves and per-location stats. Know exactly what you spend, and where.
Automatic drive logging with route maps, consumption per kilometre and efficiency scores. Every trip, recorded and analysed without lifting a finger.
Track degradation over time with capacity estimates, cycle counts and long-term trends — so you understand your pack like never before.
Acceleration, speed, smoothness and efficiency, blended into a single score with trends across thousands of analysed trips.
Lock, climate, sentry and custom triggers for charge completion, geofencing and more — with instant push notifications. Your car works for you.
