Hang the picture straight. Get the shelf level. See which corner needs a lift. Turn your iPhone or iPad into a handy bubble level and angle finder for the small adjustments that finish a job well. Measure face down, read when you lift Start a short countdown and place your phone screen-down on the surface. The result stays locked when you pick it up, keeping the rear camera bump out of the way while you measure. A phone-back guide shows which side or corner to raise. See the tilt as you work Use the circular bubble to check a surface in two directions, or the classic horizontal vial to line up an edge. Clear angle readings help you follow each adjustment, from a picture frame to a shelf or table. Keep the reading you need Hold a live measurement to inspect it away from the surface. Set a reference with calibration to compare relative angles, and choose sound or vibration cues for leveling. At home, in the workshop or setting up a tripod, keep a quick leveling tool close at hand. Choose from 28 languages and get on with the job.
