Read full descriptionHide full description
Skip retyping every flight into your logbook by hand. FlightUploader takes the CSV logs your Garmin avionics records on each flight and uploads them to your MyFlightbook logbook as pending flights — ready for you to review and confirm. Drop your SD card in once a week, point the app at the folder, and your logbook stays current. What it does • Scans a folder of Garmin CSV logs for new flights since your last upload • Filters out boot-up logs, taxi tests, and ground-only sessions automatically • Matches each flight's tail number against the aircraft in your MyFlightbook account • Uploads every selected log as a pending flight, with the original CSV attached so MyFlightbook can derive Hobbs, engine times, and route data • Optionally copies the same logs into a local folder of your choosing — handy for archiving to iCloud Drive, Dropbox, or anywhere else Designed for privacy • No backend, no analytics, no telemetry, no third-party tracking • Your account, settings, and upload history sync across your iPhone and iPad through iCloud, scoped to your Apple ID • The developer never sees your flight data Requirements • An aircraft equipped with a Garmin avionics unit that exports CSV flight logs • A MyFlightbook account (free at myflightbook.com)
