5 stars: I've been using Safelog since I started flying in 2003, initially just the PC app and later on the Android app as well. I love the app, it provides everything you'd expect from a logbook, but it is obvious that the people developing it knew what pilots need - various types of currency, filling out 8710 toward a practical test - whatever you need, Safelog got your back. These days I log my flights on Safelog, and my paper logbook is usually way behind on these, every few month I play catchup and write down the missing flights. I wholeheartedly recommend this app.
4 stars: Mostly satisfied. Used it for a month and decided to purchase a lifetime subscription, I do not regret that. It's been convenient for entries and data import was fairly simple. What am I not satisfied with? On Android, the app crashes frequently-- usually after I have entered most of the information for a flight. Sometimes it saves the info, sometimes not. I would like a simpler user interface- the "like a real logbook" is a bit of a gimmick, and worse means that I often have to scroll on TWO sets of scrollbars to see all the corners of the logbook. Also, with the redraw it takes a significant amount of time to change between pages. Since this is storing info as a database, I would love the opportunity to use a basic spreadsheet interface to minimize lag and complication. Overall satisfied.
3 stars: Android app is OK but Windows app is horrible. High time for a universal Windows companio...
