The subject of from when to when has been beaten to death on here already in numerous other posting...
All I was asking for was if someone knew of an app for recording the times with a push button once instead of having to write it all down in flight.
Up until now I have recorded my flights over the day and then recorded that as a total for the day, if it was all the same type of flying.
As for recording of lift/landing, as well as starts, which is only applicable to certain machines, I had done those in the relevant helicopters flight logs where it was necessary.
