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.
