CellArc

Battery habit workbench

Free · Designed for iPad. Not verified for macOS.

CellArc is a battery-habit workbench for iPhone owners who want more context than a single battery percentage. The app helps you review charging sessions, thermal exposure, daily drain, trip needs, and habit patterns that affect long-term lithium-ion health. Core tools: - Battery dashboard with current state and habit trend - Charging session log from plug-in to unplug - Thermal timeline with threshold callouts - Longevity score based on heat, high charge time, deep discharge, and cycle patterns - Charge profile coach with practical habit recommendations - Best-time-to-charge and trip planning helpers - App-hog session labels for user-recorded drain comparisons - Long-storage reminder and lifetime energy views CellArc is honest about iOS limits. It estimates trends from signals available to public apps and explains where iOS keeps deeper device data private. Battery logs and settings stay on your device. CellArc does not request protected device permissions, does not pair with external accessories, and does not require designated hardware in version 1.0.

CellArc 1.1 adds an iPhone Model Library (iPhone 11–17) that calibrates all energy math to your device's actual watt-hour capacity, shows your Apple-rated cycle count alongside CellArc's estimate, exports sessions/rollups/health report as CSV or text, optional smart battery alerts, and a 30-day longevity history sparkline. Fully offline — no account, no tracking.
