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.
