Supermate: EV Companion

What your driving really costs — from the charges that filled the battery — and what you save vs gas. Journeys, drivers, Recap. Your TeslaMate. One payment.

Supermate puts a price on your driving. It reads the TeslaMate server you already run and tells you what every drive really cost — from the charges that actually filled the battery — and what the same distance would have burned in gas. On iPhone, iPad and Apple Watch. It doesn't set up TeslaMate for you — you connect a server you already run. Your data stays on your server: no cloud, no account, no tracking. Every estimate wears an ≈. Nothing is invented: an unknown reads as unknown, never as zero. WHAT IT COST, WHAT YOU SAVED Each drive, month and year priced from your real charges, next to the gas equivalent at the price you set. LIVE STATUS See your car at a glance — state of charge, range, and whether it's charging, driving or parked. Follow a live charging session with the cost so far and the estimated finish time. JOURNEYS Recorded drives chain into one journey — legs, charging stops, time at the wheel and total cost. EVERY CHARGE, AT ITS REAL PRICE See where you charged, how much energy, how long and at what price. Home, work and fast chargers, all costed. KNOW YOUR CAR Statistics by month and year, battery health and degradation, charging map, activity, records and software history — every insight TeslaMate captures, made beautiful. MONTHLY RECAP Your month in a handful of numbers, ready to share: distance, favorite places, your longest day, and how you compare to your usual month. DRIVERS Mark who drove and see distance, efficiency and pace, split per person. PRIVATE BY DESIGN Supermate reads your own TeslaMate server directly. Nothing leaves your devices — no third-party servers, ever. ONE PAYMENT, NO SUBSCRIPTION Supermate Pro is a single purchase. The free tier includes the live dashboard, battery health, your last 7 days of drives and charges, and a Recap teaser. Requires your own self-hosted TeslaMate + TeslaMateApi.
