What makes a good app isn't a bunch of complicated extra stuff. A good app is one that does what it's supposed to do. This one does. I checked it against a real life orienteering compass and a USGS topographical map. Needle on app lines up perfectly with magnetic North, as it should (16 1/2 degrees declination to the right, due to the fact that our planet is not on perfect axis with the North star (Polaris) by exactly 16 1/2 degrees. What the needle of a compass points to is a large iron deposit in the crust of the North pole which shifts a little bit every year so it changes which means it doesn't stay at 16 1/2 degrees. But for practical purposes you can assume that magnetic North is more or less 16 1/2 degrees to the right of true North...I'm not making this up. Look it up. Anyways, what I'm saying is this compass lines up with magnetic North as it should.
Looks neat, but requires recalibration after every use. Need a magnetic compass to be sure the calibration is correct. Guess it's okay if you don't mind being off by 80-90 degrees, but if you're looking for an accurate compass look elsewhere or just get an inexpensive magnetic keyring compass. Hard to beat a small magnetic compass that's always correct.
Have tried a few compass apps, but gave up because they didn't do the job. This one is great. It's accurate (checked against my Silva), nicely damped, and simple! Cheers!
The only slight glitch I see is it has a very slight tendency to not hold at 0° magnetic true North. Even sitting on a very secure stationary perfectly flat surface it moves one way or the other off of 0° N. Other than that one tiny glitch it's in my opinion among the best quality apps out there to be had. I use the Motorola Droid Turbo 2 Android and yes I would highly recommend this app to anyone for business or just fun.
Very elegant design. It's not gimmicky like a lot of others. Easy to read and very similar to a good quality 'real' one. Has a smooth action and seems to hold calibration better than several others I tried. Well worth it.
This app is a simple compass which could do for a more aesthetically pleasing appearance and this Compass has issues with keeping a true magnetic north even on perfectly flat surfaces around no interference but if you like simple non cluttered apps then this app may still be for you however for a simple compass a listing price of $5 is too much fortunately I got it on sale
