Shows routes Google doesnt know

In Italy I used Google Maps exclusively, but when I arrived in Southern France Google Maps was useless. Thats when I found this gem. The best part is that it works offline. I kinda dont understand how Favorite routes (indicated by a star) works and why the length of the green line changes with duration. I understand what it means. I just dont think like that. The app is easy to use and I like that its compatible with iOS 6 (I still have iOS 7). I look forward to improvements.
