FlightLog is the most complete pilot logbook software for iPhone, iPad, and Android. More of a logbook, it comes with a lot of tools for airline pilots, professional pilots, and private pilots too.
In 1 click you can import your roster (flights are auto-populated), and once your flight is done, flight times are auto completed… nothing to do !
For Commercial Flights, you must confirm the OOOI hours (block hours) by taping on hour fields, to be considered as done.
