Given this review: "Compass calibration The map asks me frequently to calibrate my compass. Is there a way to calibrate it perfectly for a longer tenure or like a permanent calibration fix. And Sky Maps being such a useful app i guess it would be a notch up if it could show the moons of other planets as well." Would you recommend this app to a friend? Not at all, No, Maybe, Yes, or Definitely?
A:
Maybe
