Point.
Snap.
Done.
Aim your camera at the dashboard. WattLog reads every number, logs the charge, and charts your efficiency — no spreadsheets, no manual entry. All your EVs in one private history.
Every capture sharpens the next
The more you log, the better WattLog reads your car's dashboard. Every shared capture helps it learn the next driver's, too. Sharing is anonymous, optional, and off by default.
A photo of your dashboard — any EV, not just one model.
WattLog lifts every value off the photo.
Clean numbers — and a sharper read next time.
Three taps from dash to data
No forms to fill. Point at your trip screen and WattLog does the rest — capture, log, and chart every charge.
Point & snap
Aim at your trip computer. The OCR reads mileage, battery %, range, efficiency and more — and tells you when every value is captured.
Log the charge
Confirm in a tap. WattLog files the session with cost and a clean drive summary — including how much you saved versus a gas car.
Watch the trends
See efficiency, cost per mile and plug-in habits over time — so you learn what actually moves your range and your bill.
Private by design
Text recognition runs on your device. Your charge log is yours — no account is required to start tracking, and your driving data isn't sold.
All your EVs, one history
Track multiple vehicles in a single timeline. Switch cars, keep every charge, and compare efficiency across your whole garage.
Trends that teach
Efficiency, cost per mile and plug-in state of charge — charted so you can see what helps your range and what hurts it.
Built for people who like the numbers
Recognition profiles tuned for the Nissan Ariya, Nissan Leaf, Hyundai Ioniq 5, Kia EV6, and VW ID.4 — and the OCR reads any EV's trip computer out of the box. Every shared capture sharpens the next model we tune.
