Dual Level

Unlike others, I didn't have any problems using this. I was able to level all my pictures. I love it, and I won't lose this one, it's on my phone.

Levels work well, but the calibrate button need to be re-designed. As it is now, it is too easy to accidentally press. How about a small "gear" icon in the bottom corner of the screen? When the user taps it, then the calibrate button appears? If you do that, I'll bump up my rating for this app.

Needs retina display

Greatly improved since first download. Very handy app to always have with you and works well. Good buy for a buck.

Yeah you would want to use a calibrated level, but you could go to the homecenter, pick up a level, plum a surface there, calibrate, and you gots a plum level! And the "--" means it is perfectly flat, not crashed!
