Log 10 pro is a great option is you have a mac and an iPhone. Just enter your times when you get done flying into your iPhone and then sync your iPhone to your mac and your good to go.

The app for your computer is $100 in the apple app store. Log 10 pro is not the cheapest as many E-logbooks can be done for free. It's pricey, but I would still recommend it. IMO, Log ten pro is on the same level as the bose A20s are.
