Mostly Charged

Mostly Charged is a battery-first pack manager for FPV freestyle and racing pilots. Stick a QR label on every pack. At the field, scan it and tap once -- charged, flew, crashed, capacity test, or retire. The event is logged instantly with a timestamp; details like flight time, landing voltage, or IR are always optional and never block the tap. WHAT YOU GET - Scan-to-log: print QR sticker sheets on any home printer, or share single labels to your label-printer app. Labels encode a local ID only, so they work offline forever and never go stale. - Health that derives itself: cycle counts, internal-resistance trends, true capacity from your capacity tests, and depth-of-discharge history -- all computed from what you log, no manual bookkeeping. - Storage watchdog: packs left at full charge get flagged before they puff, and one batch action storage-logs the whole pile. - Over-discharge guard: landing voltages are checked against your thresholds, and repeated deep discharges nudge a pack toward retirement. - Retirement calls you can trust: age, cycles, IR trend, and puff history in one view when it is time to decide. - Backups you own: export and restore your fleet as a single file, plus CSV export for spreadsheets. PRIVATE BY DESIGN Everything stays on your phone. No account, no cloud, no ads, no analytics -- the app does not even request network access. The camera is used only to scan your pack labels and for crash photos you choose to take. Built for the flight line: big touch targets, numeric keyboards where you type charger numbers, dark mode, and a fast path that is two taps after scan.
