Volti — EV Charging Log - Track every EV charge: kWh, cost & battery health

Volti turns EV charging into clear numbers privately. Log any charge in 10 seconds (kWh, price, AC/DC), and Volti calculates your real kWh/100 km, cost per km, and battery State of Health. Why it's different: - 100% on-device no account, no cloud, no sign-up - Multiple cars, each with its own currency (30+) - AC vs DC cost breakdown + charts by day/week/month/year - CSV/PDF export, home-screen widget, 7 languages Free. No more spreadsheets just your charging history, finally making sense.

Hey Product Hunt! 👋 I drive an EV and kept asking myself the boring-but-important questions: how much am I really spending per month? What's my actual kWh/100 km? Is my battery slowly degrading? I tried tracking it in spreadsheets and gave up after two weeks. So I built Volti — a logbook that takes 10 seconds per charge and turns it into real numbers: cost per km, AC vs DC comparison, seasonal efficiency, and a battery State of Health estimate. Two principles guided me: 1. Privacy first — everything stays on your device. No account, no cloud, no sign-up. 2. Effortless — quick templates, auto-fill odometer, a home-screen widget. It's free, on iOS and Android, in 7 languages. I'd love your feedback — especially: which metric would you want to see next? 🔋
