Meet Volt — your battery's new best friend.
Volt is a cute battery companion that reacts live to your iPhone's charge level, helps you keep a healthy 20–80% routine, and turns good charging habits into a daily streak. Everything stays on your device — Voltsy has no account and no backend.
Voltsy uses only Apple's public battery APIs. It never claims to read your exact battery health percentage or cycle count — every care figure is a clearly-labelled on-device estimate.
