The app works very well and it does its job.
The only limitation I saw is in using it as the only way to take pictures during trips.
The app save the pictures you take in the camera roll but the saved pictures do not have their geolocation information. So when you look at them via the standard image app you are not able to view them correctly placed on the map.
I hope developers will fix this in a next release.
