Your car's screen shows the consumption of the moment, then moves on. wattata keeps every drive and every charge of your electric car, and turns them into clear numbers on your iPhone: what each drive used, what each charge cost, and where your battery spends its time.

HOW IT WORKS
wattata comes as two apps. The car app, installed on the car's own screen, quietly records while you drive and while the car charges. This iPhone app analyzes what it recorded. Scan the code shown in the car with your iPhone: the car and the iPhone link up directly. No account, no password.

EVERY DRIVE
• The energy used, your efficiency, regeneration and what the drive took from the battery
• The curve of each drive: power spent, regen and elevation
• The map of each drive, its route colored by what each stretch used or gave back: touch it, or replay the drive, to read the speed, power, efficiency and battery at that moment
• The cost of each drive, at the price of your charges
• Each month: the distance, energy, efficiency and cost

EVERY CHARGE
• The energy added, the power, the range gained and what it cost
• Charging profiles for Home, Work or a network you use, each with its price per kWh, fixed or by the hour: each kWh takes the price of the hour it went in

EFFICIENCY
• Your efficiency day after day, next to your best week
• What had an impact over the last 30 days: regeneration, ascent, time stopped, accelerations, temperature
• Where you stand among drivers of the same model, if you turn on the fleet comparison

BATTERY
• The time your battery spends at each charge level, month by month
• Your charging habits and the energy lost while parked
• An estimate of the battery's real capacity
• Tips drawn from what was measured, one at a time, and nothing when all is well

FOR WORK
• Tag your work drives Business, and the month exports on its own as CSV
• Give a trip a name and dates: its drives and charges gather on one page, and a business trip comes out as one PDF report

ON THE IPHONE AND IN THE CAR
• CarPlay: your current drive on the car's screen
• Widgets: the car's charge and range, and your week's efficiency, on the Home Screen
• Locate vehicle: where the car is parked, if you turn the option on
• Weather: its effect on your range, tonight and tomorrow
• Mileage forecast: how far you'll have driven by December 31 and, on a lease, against its mileage cap

YOUR PRIVACY BY DESIGN
The analysis happens on your iPhone. No account, no analytics kit, no crash reporter. Two options, off until you turn them on, send a minimum to our servers: the car's last position for Locate vehicle, and an efficiency summary for the fleet comparison.
wattata gives you no score and sends your car no commands: the car app only reads its battery and driving data.

COMPATIBLE CARS
Electric cars from Polestar, Volvo, Chevrolet, Cadillac, GMC, Honda Prologue, Acura ZDX and more. Not every model or year can install the car app: look for wattata on your car's screen.
