User Reviews

I’ve tried many compass / altimeter apps, and I gotta say I love this one the most. We all know that compass apps are no high-tech. So i think a lot of developers over-design it to make it look nicer to stand out. But tell you what, among all fancy looking ones this simple design stood out the most for me! Also the amount of features are just right (altitude, temperature and location and of course heading) though it may be nice to include wind direction and air pressure data. (But dont compromise the current simple design please!!). Love it. It’s unmatched. Well done!
