Bubble Level & Angle Meter

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.
