FLYGARN  I feel the need to add a comment here since the remarks seem very old.

I bought LogTen at 4.7 because I had tried v2 and 3 demos and didn't really like what I saw. However with this version and the SQL database I think performance and features are great. I've since purchased the iPhone addon app and I log all my flights right there at work. When I get home I just sync it up with my mac and print out the pages from time to time. It's a great timesaver for me logging 80-90 hours a month, but for casual users it's probably overkill. If you're a pro however and using a mac this is a solution I would recommend.

LIAM0008  I'm using logten pro since version 2 and I always had problems with it. I updated to version 3 and still a lot of bugs... Mainly random loss of data. The thing is, being a mac user, if you want an "electronic" logbook you don't really have the choice. Then it's up to you. I spent 150 $ (version 2 + update to version 3) for a software that is not really functionnal and such a huge P I T A. If somebody could have told me... :(  
(Version 3.1)

ANONYMOUS  Could be an absolutely killer app, but way too slow and buggy. Crashes about every fifth time it's opened, sorting with filters is painfully slow, opening takes over a minute to load data, which will only get worse as more data is added.

For a commercial offering at a high price ($89 USD), it's not really a good value...developer is trying hard but you can't take ppl's money for something so unstable.

Design/GUI is beautiful but database implementation is brutal...reading between the lines (developer also has design house, great website, great prog icons, etc) I'd say the creative side is A+ but the technical side is an F...stick with Excel.  
(Version 2.7.7)

JONATHAN CARDOZO  Logten has everything I need as a pilot to keep my logbook online. Much better than paper because I can search, and keep lists.

I tried to keep my logbook in a spreadsheet, but LogTen makes it much easier. Flight entry is much faster than doing it manually. I especially like the "smart" reports in the pro version, helpful for keeping track of my flights in different types of aircract.

The best thing about logten, though is that the developer is so responsive. A constant stream of updates and additions based on user feedback. Very cool.
