Have you ever used a level to see if an object is perfectly level? Did you know you can do the same with your iPhone? From your iPhone Home screen, open the compass app and you’ll notice 2 dots at the bottom. If VoiceOver is, on flick to th left with three fingers. If voiceover is not on, flick with one finger to the left to reveal the level part of the application. Once you are there, put the iPhone up against the object you wish to test. Speech will tell you the degree of The object you are trying to test. If you are not using speech, the amount of degree will be shown on the screen. If the amount is 0°, your item is level. If voiceover is on, the app will tell you if you are measuring vertically or horizontally.
