CellArc for iOS: Limited-Time Free Download

CellArc transforms your iPhone’s battery health from a one-number guessing game into a full habit workbench — and it’s currently free (was $0.99). Most battery apps just show a percentage; CellArc analyzes charging sessions, thermal exposure, daily drain, and long-term cycle patterns to give you a clear longevity score and personalized charge coach. It’s honest about iOS limitations, explaining where data remains private, so you never have to worry about hidden permissions or external accessories. If you’ve ever wondered why your battery degraded faster than expected, CellArc provides the context you’ve been missing — all on-device and offline. On a practical level, the app helps you plan the best time to charge before a trip, review which apps drain the most power with user-recorded session labels, and receive reminders for long-term storage. The thermal timeline with threshold callouts is a rare find, making it easy to spot overheating incidents that silently damage lithium-ion cells. For anyone serious about stretching an iPhone’s battery lifespan, CellArc offers insights usually reserved for pro diagnostic tools. Grab it now while it’s free — this kind of depth rarely comes without a subscription.
