Your logbook never touches our servers.
Every flight lives in your own iCloud account, encrypted by Apple. We could not read your logbook if we wanted to, and we designed it that way on purpose.
The pilot behind the logbook
Three decades in aviation. A lifetime in software.
Portrait en route
Michael Lyndaker
Founder · Gulfstream G600 pilot
My aviation career started in 1993, enlisted in the US Air Force as an avionics technician on the F-15E Strike Eagle. Four years of keeping fighter systems honest taught me two things: precision matters, and good tools are everything.
After the Air Force I went to Embry-Riddle Aeronautical University in Daytona Beach, where I did all my flight training and graduated in 2000. I stayed on as a flight instructor for nearly three years, then flew Cessna 402s out of Fort Lauderdale to the Bahamas, building multi-engine time the old-fashioned way.
That led to the airlines: Continental Express, later ExpressJet, flying the Embraer 145. I upgraded to captain in two years. After four years in the airlines I moved to corporate aviation, and that’s where I’ve been ever since: the Falcon 900EASy, the Falcon 7X, the Gulfstream G280, and today the Gulfstream G600.
The other half of the story started earlier. I’ve loved computers since I was eight years old, when I got my first one, a Commodore 264. Ever since, my free time has gone into building things with software.
KármánLogs is where the two halves finally met. Every logbook on the market frustrated me: cluttered, dated, built like spreadsheets with wings. I wanted something fresh, smart, and easy. So I built it.
Over 10,000 hours of flying live in my own logbook today, and every one of them is in KármánLogs.

Why “Kármán”
Named for the line where the sky ends.
The Kármán line sits 100 kilometers above the Earth, the internationally recognized boundary between aviation and space. Every hour in a pilot’s logbook is flown beneath it, and every career builds toward it.
It felt like the right name for a logbook: a precise, agreed edge against which everything below is measured.
How it’s run
Three promises, kept in the architecture.
No lock-in
Leaving must always be easy.
Automatic encrypted backups and full CSV export, any time, on every tier. A logbook that holds your career hostage is not a logbook, it is a ransom note.
Support
A human answers within 24 hours.
Every support email is read and answered by the person who built the app and flies with it. No ticket black hole, no chatbot runaround.
