I used LogTen Pro for a year and found it was good but had some issues. It was very easy to create eroneous entries and input errors. I transitioned to Safelog (pilotlog.com)

I am very happy with it and the price is very good. What I like best is there is a web based way to input data, it also has data migration from other services, apps for all mobile devices, etc.

the link above is a link that will give you (and me) a subscription extension if you decide you like it. It is also free for quite a while too but I don't recall how long.
