Bubble Level
Measure level and tilt using the device motion sensor.
Allow sensor access to start measuring.
What is this?
The Bubble Level uses your smartphone's tilt sensors (gyroscope/accelerometer) to check whether the surface your phone rests on is level. Like a physical bubble level, when the dot inside the circular dial sits at the center, the surface is level. Handy for hanging frames, leveling shelves, or setting up furniture.
How to use it
Tap Allow Sensor Access to let your browser request orientation sensor permission. Once granted, the dot inside the circle moves as you tilt your phone, and the horizontal/vertical tilt angles (in degrees) update live. When the dot lands inside the center target ring, it turns green to indicate a level surface.
Real-world uses
Use it to level a picture frame or shelf on the wall, set up furniture or appliances evenly, or check that your camera is level before a shot. For precision work, use it alongside a physical level as a reference only.
