This is a great app. No permissions needed, no BS, and it's easy to use. It seems to work on magnetic lines of force, like a traditional magnetic compass. The downside to that is you have to make a correction for your local magnetic variation if you want to use it with a map based on true north. If the developer would let you store that correction, I would give it 5 stars. Also, your accuracy is going to suffer if you're near large iron or steel objects. In the great outdoors, no problem.

No luck. Made dozens of figure 8s (like writing on a chalkboard, as someone suggested). No luck. It still tells me the sun rises in the south. Never did find the three bars several users pointed to whose alignment (or lack thereof) would indicate the level of calibration (and, yes, I could really use one of those bars right about now). On the plus side, it's free.

Works great if you are not in close proximity to a magnet of even low positive draw. So, using in a automobile with a system that has anything like a midrange speaker in the door panel is going to pull it and point the N to the speaker it's closest to. But if you get out and walk around with it in your hand and avoid anything magnetic, it works perfect. Actually, it's a little bit too. Sensitive and can be useful in a car if it wasn't. Or had a setting to lower the sensitivity adjustment.
