LevelMaster turns your phone into a precision spirit level and angle meter, using the built-in motion sensor — no extra hardware needed. BUBBLE LEVEL • Circular bubble level for flat surfaces — lay the phone on a table, shelf or countertop • Bar bubble level for vertical surfaces — hold it against a wall, door frame or picture • Automatically switches between flat and vertical modes as you move the device ANGLE METER • Large protractor-style gauge with a live degree readout • "Set as 0°" lets you zero out any starting angle — handy for measuring a slope or a change in angle (e.g. a ramp or a roof) LEVEL ALERT • A confirming beep and a light vibration the instant the device becomes level • Turn the beep or vibration off independently in Settings CAMERA OVERLAY • See a level line through the camera while you hang a shelf, a frame or a piece of art • The line turns green the moment it's level CALIBRATION • Correct small sensor offsets against a known-level reference, per device MADE FOR EVERYONE • Light & dark themes with multiple accent colors • English and Japanese • Keep the screen on while measuring PRIVACY FIRST • Works fully offline. The camera is used only to overlay the level line — nothing is ever captured, saved, or sent anywhere. No account, no cloud, no tracking. Great for DIY projects, hanging furniture after a move, and checking a boat or dock is level while fishing. Note: readings are approximate and depend on your device's sensor. LevelMaster is intended for everyday DIY use, not for professional or regulatory measurements. Free, supported by ads.
