5 stars: I find it amazing that works on a plane. it reassures me that we are still in the air and we are flying and we are level. this is a godsend.
5 stars: Should be turned into a weather and gps map. Three or four things in one app.
5 stars: Just installed from Face Book. Really like it.
4 stars: I've been using this app professionally (field engineering) for over a year on iPhone, and the functionality is the same on Android. The ability to send/receive GPS locations as KML files is *very* useful, especially when paired with a high accuracy GPS device such as the Bad Elf GNSS Surveyor or Trimble R2. However, there is one issue where the app crashes when attempting to share \
3 stars: 1.Not intuitive. I simply do not understand how it works. I can set a point, but that's all. None of the features in the video are in the menu. If this is supposed to be a puzzle, success! 2.when I arrived at the forest in my city, it said no maps available, although I loaded the app before my departure from home, thinking it would load the map for my region. But it didn't.
5 stars: I really love Spyglass. Well designed. If the font size could be made adjustable for easier reading for my poor eyesight, I'm just one person, may be just fine for others. You have a lot packed into this app. Lots of information.
5 stars: this is the most complex and hard to understand compass app ever, take a while for me to figure out how to use it and find how awesome this app is, btw...
