Your logbook should do more than store numbers. It should tell you whether you're current, whether you're legal to fly tomorrow, and how close you are to your next certificate. KármánLogs answers all three the moment you log a flight. From first solo to the left seat, it's a complete logbook built by pilots, for pilots. LOG FLIGHTS IN SECONDS • Fast, flexible entry with smart defaults • Enter your Out, Off, On, In times and the app calculates block time, flight time, night time, and day and night takeoffs and landings for you • Track crew, approaches, holds, and remarks on every leg, with PIC, SIC, instructor, and student roles • Aircraft profiles with FAA registry lookup • Endorsements with instructor signatures, training milestones, and carry-forward totals from an earlier logbook ALWAYS KNOW WHERE YOU STAND • FAA currency at a glance: passenger carrying (day and night), IFR, flight review, medical • Part 121 and Part 135 currency, duty, and rest tracking for professional pilots, so "am I legal tomorrow" takes one look, not a spreadsheet • Duty time is fully automatic. Your duty period opens, groups multi-leg days, and closes itself from the flight times you log, then reopens if you fly again before a legal rest • A dashboard you design: currency status, totals, METAR and TAF weather, closest airport, sunrise and sunset, Zulu time, and more SWITCHING APPS? BRING EVERYTHING • Dedicated importers for LogTen, ForeFlight, and FLYLOG.io exports capture the full record, not just the basics • AI-assisted mapping imports CSV exports from nearly any other logbook • Every import is protected: automatic backup beforehand, duplicate warnings, and one-tap Undo This Import STILL ON PAPER? SCAN IT • Photograph each page of your paper logbook and AI reads the rows into digital entries • Verify every entry row by row before it saves • Your original page photos stay attached for reference FOR PROFESSIONAL CREWS • Log Airline Flight: enter your flight number and date, and the app fills in the route, all four Out/Off/On/In times, and the exact aircraft you flew, added to your fleet automatically • Retrieve from ADS-B: pull the real Out/Off/On/In times for your tail number from flight tracking data. No hardware, no setup, covering about the last 10 days • Scan from FMS: photograph the FMS or a touchscreen controller and the app reads the times, tail number, and airports into a new flight • Satcom Direct integration pulls OOOI times straight from the aircraft datalink • Duty Period Report: a print-ready FAA-audit PDF for any date range, with rest and rolling limits checked against the exact FAR requirement REPORTS AND EXPORTS • FAA 8710 experience summary, ready for your next application • PDF logbook export, plus CSV export free on every plan • Logbook display styles, including an ATP and military profile YOUR DATA, YOUR ICLOUD • Your flights sync privately through your own iCloud, across all your devices • Automatic backups, restore anytime • Export everything whenever you want.
