Turn your phone into a precise bubble level and angle meter. Level a shelf, hang a picture straight or check a slope in seconds, with a clear reading you can trust. One clean tool with four ways to measure: a classic spirit level, a 2D surface level, a digital inclinometer and a camera level. LEVEL A classic single-axis vial for shelves, picture frames, cabinets and countertops. Turn the phone to landscape and rest its edge against a wall, door frame or post to check that it is plumb (vertical). 2D SURFACE LEVEL A round bubble that levels both axes at once. Ideal for tables, tripods, a washing machine, a pool table or levelling a camper or RV. ANGLE METER A numeric protractor and inclinometer for ramps, roof pitch, stairs, drainage slope and miter cuts. Works in portrait and landscape. CAMERA LEVEL A live viewfinder with a crosshair keeps horizons and verticals straight while you frame photos of buildings, interiors and landscapes. BUILT FOR ACCURACY • Calibrate on a known flat surface for the most accurate readings • HOLD freezes the value, so you can read it after lifting the phone • Relative zero: set any surface as zero and measure the difference from it • Beep and vibration the moment the surface is level • Screen stays awake while you measure • Units: degrees, percent grade and mm/m • Adjustable precision: 0, 1 or 2 decimals SAVE YOUR MEASUREMENTS Save levels, angles and camera shots to History, add a note, and see a pass or fail mark for each result against your own tolerance. MAKE IT YOURS Light and dark theme, several level styles (Classic, Vial, Ring, Horizon) and more than 70 languages. GREAT FOR • Hanging pictures, mirrors, TVs and shelves • Installing furniture, kitchen cabinets and appliances • Laying tiles, flooring and decking • Levelling a camper, RV or travel trailer • Setting up a pool table or a camera tripod • Construction, carpentry and home DIY projects Keep a bubble level and angle meter in your pocket for every job around the house.
