Leccy
EV charging cost tracker · Full-stack PWA · v1.1.1
Leccy came out of frustration with the lack of simple tools for tracking the real-world cost of charging an electric vehicle across multiple tariffs and locations. Home off-peak, rapid public chargers, and everything in between — it all adds up differently, and most apps either ignore it or bury it in subscriptions.
The brief: a clean, fast web app that installs as a native-feeling PWA on both Android and iOS, lets you log a session in seconds, and builds up a genuinely useful picture of your charging habits and efficiency over time — including more advanced metrics like battery health proxy, thermal impact on range, and GOM accuracy.
