About

Supermate

Supermate tells you what every drive, journey and charge of your electric car really costs, at your real tariffs. On iPhone, iPad and Apple Watch. Compatible with Tesla Model 3, Model Y, Model S and Model X. TWO WAYS TO CONNECT โ€“ Your own TeslaMate server with the free TeslaMateApi add-on. The app helps you install it, and your data stays on your server. โ€“ Supermate Cloud: connect your car without a server of your own. During the free launch, access is by invitation and includes every Pro feature. Drives and charges are recorded by your server or by Supermate Cloud; the app syncs them. WHAT EVERY MILE COSTS Each drive is priced from the energy in the battery, at the cost of the charges that actually filled it. Consecutive drives chain into one journey, with its legs, charging stops and total cost. It all adds up into monthly and yearly totals. Every estimate wears an โ‰ˆ. An unknown reads as unknown, never as zero. YOUR TARIFFS, AS THEY ARE A price per place: home, work, public chargers. Each tariff change is kept with its date, so today's price never rewrites the past. Time-of-use bands for off-peak plans, different on weekdays and weekends, and Spanish national holidays can count as weekend. If your server already recorded a charge's cost, that is what counts. And if your car has free charging, those sessions count as free. EVERY CHARGE, IN ITS PLACE The pauses of a smart tariff fold into one session. See where you charged, how much energy, how long and at what price, with your charging sites on a map. CHARGING, LIVE Your car at a glance: battery, range, and whether it is charging, driving or parked. While it charges, the Lock Screen and Dynamic Island show the cost so far and the estimated finish time, and Apple Watch shows the level and the cost. Widgets for iPhone and complications for the watch. YOUR BATTERY'S HEALTH Today's capacity and range against factory figures, and how they change month by month. YOUR CAR IN NUMBERS Monthly and yearly statistics, personal records, an activity map and software update history, with a heads-up when a new update is available. DRIVERS Mark who drove. On routes you repeat, the app suggests the usual driver and you confirm. Compare drivers on the same route, where the road cannot explain the difference. YOUR MONTH IN A RECAP Your month in a handful of numbers, ready to share: distance, favourite places, your longest day, and how it compares to your usual month. AND, AS A BONUS, VS GAS What the same distance would have cost in gas, at each month's average price where public data exists, or at the price you set. PRIVACY With your own server, the app reads it directly: your car data never goes through third parties. With Supermate Cloud, it is stored on servers in the European Union and you can export it any time. ONE PAYMENT, NO SUBSCRIPTION Supermate Pro is a single purchase. The free tier includes the live dashboard, battery health, the last 31 days of drives and charges, and a Recap preview.
