What it does
A spirit level is one of those tools every home needs but rarely anyone remembers to own. Bubble Level turns your Android into a precise spirit level you always have with you.
Built for real tasks
Whether you're hanging a picture frame, installing shelves, leveling a washing machine, or checking if a surface is truly flat, Bubble Level gives you an instant, reliable reading.
How it works
Your phone's accelerometer measures gravitational force in three axes. Bubble Level uses these readings to calculate the tilt of your device relative to horizontal and displays it as a classic bubble-in-tube visualization, plus a precise angle in degrees.
Two modes for two needs
Switch between horizontal mode (is this surface flat?) and vertical mode (is this wall perfectly plumb?) with a single tap. The bubble responds in real time as you move the device.
Lock and compare
Found the right angle? Lock it in place and use it as a reference to match other surfaces to the same tilt - useful for matching the angle of multiple shelves or picture frames.
