MccPilotLog, desktop version is free with unlimited entries so you can convert your whole logbook. You can just use desktop version until you decide to do mobile one as well. They will walk you through and convert other electronic versions or excel spreadsheets for you for free. The paid version is one time fee, 80.00, and you can connect to mobile version, download flights/schedules from your airline. Supports all mobile and desktop platforms. I used an older version of Logten Pro before they charged for subscription fee. MccPilotLog is a better product for much less. I use it on macbook and iPhone, but it’s also on windows and android.

To the first who replied. They can convert what you got on your logtenpro to MccPilotLog in like ten minutes.
