Works great if you fly only one particular type, while for this price you expect it to work good for everything!
Also it should know already a lot about the types you can select,
(E.g. When you put Boeing 737, of course it has a retractable gear and every minute you fly is actual instrument, but still you need to select it everytime.
So 4/5 stars because of the price and that there is still quite some stuff to improve!
+:
Good overview
Showing limits
Perfect if you fly one type
Smart groups, which help you to fill your resume correctly
Syncing
Perfect if your handwriting is bad and your logbook is a mess
-:
Price
Some options missing
Very easily to delete your flights(shouldn't be possible after you lock it)
When flying more types you have to adjust everything everytime
But don't hesitate to buy it, I guess they will improve it to become the best log app available :)
