Log Ten pro is great. I downloaded the universal version for Ipad and IPhone. The customer service reps are great and answer questions within 24 hrs by email.

I had log book pro on the PC but it doesn't even compare. If you have logbook pro you just need to export your logbook and email the file to Log ten. They will convert the file for you and provide a link to click which import everything into your Ipad or Mac.
