CellArc turns your iPhone's battery into something you can understand and plan around β€” on device, with no account, no ads and no subscription. NEW IN 4.0 β€’ Battery Health Log β€” iOS shows Maximum Capacity only as today's number. Log it from Settings > Battery > Battery Health (plus the cycle count on iPhone 15 and later) and CellArc fits a trend from your own readings: loss per year, cycles per month, loss per 100 cycles and a projected date for reaching 80%. β€’ Siri & Shortcuts β€” "Battery Outlook" summarizes your level, today's recorded discharge and latest Maximum Capacity. "Log Battery Level" records a sample even while CellArc is closed; add it to a Shortcuts automation such as "When iPhone is connected to power". "Log Maximum Capacity" adds a health reading by voice. β€’ Full backup & restore β€” one JSON file with your samples, charging sessions, daily rollups, health log and routine trials. Restoring only adds missing records; it never deletes or overwrites. β€’ Redesigned navigation β€” the system tab bar with five clear destinations, and every Power Lab tool opens with a real back button. Higher-contrast text, Dynamic Type support and a calmer iPad layout. WHAT CELLARC DOES β€’ Dashboard with live level, Battery Action Plan and a 7-day longevity trend β€’ Live Forecast: time to full and time to empty from recent movement β€’ Charging sessions with time to 80%, peak thermal state and charge-speed trend β€’ Longevity score, 20–80% band coach, drain analysis, usage rhythm and heat exposure β€’ Scenario Studio and Routine Trials to test a changed habit against your own data β€’ Trip Planner with power-bank sizing, Best Time to Charge, Storage Mode reminders and Lifetime Energy β€’ Offline Charger Guide and a 23-topic Battery Field Guide with Apple sources β€’ CSV, text and PDF reports HONEST ABOUT iOS LIMITS iOS does not let apps read Maximum Capacity, cycle count, temperature or per-app power. CellArc samples the public battery level and thermal state while it is open (or when your shortcut runs), labels estimates as estimates, and uses the readings you enter for health trends. It is not a diagnostic or service tool. Everything included β€” one purchase, no subscription. iPhone and iPad.
