Bubble Level

Turn your Android phone into a clear, responsive bubble level.

Bubble Level uses your device's accelerometer to display tilt, angle, slope percentage and millimetres per metre in real time. The full-screen display works in portrait and landscape orientation.

Features:

• Live tilt and angle readings

• Slope shown as a percentage and mm/m

• Portrait and landscape support

• Rotation lock

• Vibration and optional sound feedback when level

• 45° feedback for common angle checks

• Simple, full-screen one-tap controls

Sensor accuracy depends on your device and its calibration. For critical professional measurements, verify results with a certified tool.
