Coming soon to the App Store and Google Play
Battery-first pack management for FPV pilots.
Stick a QR label on every pack. Scan it at the field, tap once, done — the app does the bookkeeping a charger can't.
A one-time purchase. No subscription.
How it works
Scan, tap, logged. The whole loop is two taps.
Scan the sticker
Every pack gets a printable QR label that encodes a local ID — it works offline forever and never goes stale.
Tap the action
Charged, flew, crashed, capacity test, or retire. Logged instantly with a timestamp. Details are always optional.
Read the trends
IR creep, true capacity, cycle counts, and retirement calls emerge from what you log. No manual bookkeeping.
What the charger can't see
The health engine keeps score so you don't have to.
Scan-to-log
Print QR sticker sheets on any home printer, or share single labels to your label-printer app. Two taps after scan is the whole flow.
Health that derives itself
Internal-resistance trends, true capacity from your capacity tests, depth-of-discharge history, and cycle counts — computed, not typed.
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; repeated deep discharges nudge a pack toward retirement.
Any printer works
Avery-style sticker sheets from a home printer, or a single label shared straight into Brother or Niimbot apps.
Backups you own
Your fleet exports to a single file you control, and restores from it. CSV export for the spreadsheet crowd.
Nothing leaves your phone.
No account, no cloud, no ads, no analytics — the app doesn't even request network access. The camera scans your labels; that's it.
Read the privacy policyComplements the charger, doesn't compete with it
The charger already storage-charges packs and shows mAh and IR — the app owns what the charger can't see: which pack is which across the whole fleet, how each one is trending over months, and when a pack has earned retirement. Built for the flight line: big touch targets, numeric keyboards where you copy charger numbers, dark mode, and a fast path that never puts a form between you and flying.
