Voltsy is an iPhone app that turns battery care into a friendly habit with Volt, an animated battery character that reacts live to your charge - happy in the healthy 20-80% zone, sleepy when low, and dramatic at 1%. It sends charge alerts to unplug around 80%, tracks your charge history, and rewards a daily care streak, with a Charging Live Activity on the Lock Screen and Dynamic Island plus a Home Screen widget. Voltsy is radically honest: because iOS does not let apps read Apple's official battery health or cycle count, every figure is a clearly labeled on-device estimate. WHAT'S NEW IN VOLTSY - Charge alerts: a friendly nudge to unplug around 80%, and a heads-up when you're running low. - Volt's Care Tips: simple, science-based habits to keep your battery healthy - minus the fear-mongering. - Charge history: see your charge level over time at a glance. - Honest by design: a clear explainer of what iOS does and doesn't let any app show. WHY VOLTSY - A character, not a wall of numbers. - A daily care streak with a free Power Nap freeze. - Keep it in the healthy 20-80% zone with a friendly ring. - Charging Live Activity on the Lock Screen and Dynamic Island. - Home Screen widget. - Achievements for good charging habits. RADICALLY HONEST Voltsy never pretends to read Apple's official battery health or cycle count - iOS doesn't allow it.

VOLTSY PRO - pay once, keep Volt happy forever - Zero ads, forever - Full charge history - Custom alert thresholds - Unlimited Power Nap streak freezes One-time purchase. No subscription, ever.

Verdict
The clearest difference is in-app purchases: E at none against Voltsy's 1. E also leads on ads (none vs shown) and device support (3 vs 1). Voltsy's advantage is update cadence (every 3 weeks vs every 8 months). On price there is nothing between them.
