MeasureKit - Ruler & Level

MeasureKit puts three everyday measuring tools right on your screen — no physical ruler needed. FEATURES • Screen Ruler — real mm/cm scale drawn to your phone's actual screen size. Drag two caliper cursors to measure length precisely between any two points. Calibrate against a real ruler for even higher accuracy. • Protractor — drag two arms to measure any angle from 0° to 180°. Switch between single, double, or no pointer. • Bubble Level — uses your phone's accelerometer to measure roll and pitch in real time. Center the bubble and know your surface is level.
