A bubble level that guides you by sound, plus inclinometer, plumb and square.
Hanging a picture on your own, both hands busy, squinting sideways at your phone. That is exactly where every digital level falls apart. SonoLevel guides you with sound: the closer you get to level, the faster the beep. When you are there, a continuous tone. Keep both hands on the picture and level it by ear. FIVE MODES • Level: a two-axis bubble on a target, with pitch and roll shown separately • Inclinometer: the tilt along the phone, for ramps, pipes and stairs • Target: reach an exact non-zero value, like a 2% slope or 45° • Pro: the full readout, two decimals, each axis, stability and the best value reached • Camera: the level over the camera image, to line things up without resting the phone TOOLS FOR REAL JOBS • Which leg?: to level a four-legged table or cabinet, it tells you which leg to raise and by how much • Protractor: the angle between two surfaces • Plumb: whether a wall, column or door frame is plumb, and which way it leans • Compass: the heading, compensated even when the phone is not flat • Square: mark 90°, 45°, 30° or 60° on the floor or a table • Log: every saved measurement, with name, date and photo BUILT FOR WHEN YOU CAN'T SEE THE SCREEN • Hold: freezes the reading when the phone is behind furniture or on top of a wardrobe • Read-aloud of the value, in English or Spanish • Rhythmic vibration that follows the sound, for noisy building sites YOUR WAY • Units: degrees, percent, millimetres per metre or 1:x • Adjustable tolerance for what counts as level • Light and dark theme, with several colour palettes • Simple or precise two-position calibration that cancels the sensor's own error • Quick-access home screen widget • Step-by-step help on every screen STARTS SILENT Sound begins when you tap "Start". No beeping the moment you open the app. WORKS OFFLINE Uses only your phone's sensors. No ads, no sign-up, no data collection.
