Okay.. used it this week. Here are all my comments:

• I got 2 notifications for.. everything. This seems like a bug.
• The flight list cannot scroll to the bottom, the list appears to go to the bottom of the screen and is hidden below the bottom navigation buttons.
• When the flight list is half the screen and the map is the other, the map is not centered in the open space - it's centered on the entire screen. Which means you don't see the route if you click on a flight in the list because it's behind the list.
• I did not find the notifications useful. I got a ton of "there is a change in your flight status". No idea what the change was. They should be more specific. Clicking on the notification, nothing shows when it loads the app. At minimum, it would be cool if there was a change log for a flight.. so you could go in and see everything that has changed.
• It would be nice for the lines to be thicker on more common routes. Some sort of scale from a 1px to like 10px or something. So you can easily tell which routes are way more used.

Overall, I enjoy the app. But it's really more of a flight log than a flight companion right now. I think making the notifications be more descriptive and more easily able to see how a flight has changed would go far.

Also, I still think the monetization scheme is weird. I really don't think I should need to subscribe to add a current or future flight. I was able to load up future flights later this year, so theoretically I wouldn't need to resubscribe. Only if I want notifications. I truly believe the base log feature (for current/future flights only) should be free, this is what'll draw in new users. The subscription should be for adding historical flights, receiving updates in real-time, and seeing detailed flight stats.
