Great level. User interface needs work. – STANLEY® Level Review

Works very well as a level. However, it unnecessarily flips your screen orientation, and it's difficult to close. You can't simply swipe to background or close it easily. After a lot of pointless swiping I finally had luck with a two-finger pinching gesture, but there's no instructions or guidance to clue you in. I appreciate a free tool, but this one was frustrating. Stick with Apple's built-in measure tool until they polish this up.
