I'm not a MAC guy (at least yet), so I've used LogbookPro for several years now and have been fairly happy with it in general.

That said, I'm not at all pleased with their program for the Android platform - to utilize it I have to pay a monthly fee for the cloud sync. I don't need cloud sync (other than to utilize my phone to enter trips on), and I'm confident I could accomplish a sync via cable or bluetooth if they would make provision for that. I'd happily pay a resonable one time fee to purchase the program rather than shell out every month for the stupid cloud I don't want. To me that's just exploiting me and forcing me to pay you every month - two thumbs down. As a result, if I ever get a (Mac/iPhone/iPad) I'll take a closer look at LogTen.
