Bubble Level – Spirit Level

A bubble level, spirit level and angle finder in your pocket.

Set the phone on a shelf, a windowsill or a door frame. The bubble tells you if the surface is level. The angle readout tells you how far off it is when it is not.

What it does
- Bubble level with a horizontal vial and a vertical vial: flat surfaces and plumb edges, no second tool
- Angle readout in degrees, with decimals
- Lock the bubble, then read the value after you pick the phone up
- Sound on level, so you can watch your hands instead of the screen
- Calibration takes a few seconds on a flat surface you trust
- Viscosity setting: a calm bubble for fine work, a quicker one when you are moving around
- Full screen mode for a bigger vial

Where it helps: hanging a picture straight, fitting shelves, checking a washing machine sits flat, setting a fence post, seeing whether a wall is plumb before tiling, checking a screen or a desk is not tilted.

Readings come from the phone's accelerometer, so calibrate first on a surface you trust. After that, two readings from the same spot should agree.

No account, no clutter. Open it and put the phone down.
