Dual Level‪-‬ 4+

From what I've seen this app seems to be better than the original iHandy level app that you will often see. The readouts seem to be much more sensitive and precise. I just wish there was a way to automatically set them both back to the default level setting after you've adjusted it for a custom angle reading.

It is pretty to look at, and showing both axes in digital and analog is a good concept. Development suggestion: it would be handier if it was able to rotate itself on the screen, so numbers would stay right side up. Also, remove any active touch-links from the screen. On my iPad 1, accuracy is off between 1-4 degrees depending which side I measured, which would be good enough for leveling some things, but was not close enough for hanging a picture. I think this is a hardware flaw, not software. More annoying, if I press it against an object, I activate the Power Down button or the volume button, or my thumb on the screen touches something, sending me off to the app store, another app, or the Home screen.

I like it because it is simple, accurate and easy to use. 4.5 stars. I used it to hang several pictures in my living room and bedroom.
