Level¶

A spirit level: a bubble moves against the pull of gravity and turns green when the watch lies level. Ported from wasp-os's level app.

Using it¶

Lay the watch on a surface. The bubble moves towards the higher side, and turns green within a few pixels of the centre.
Tap anywhere to open the menu, which reminds you to calibrate on a flat surface:
Calibrate takes the current reading as level. Do this with the watch on a flat surface.
Reset forgets the calibration.
Cancel goes back without changing anything.
The calibration is remembered. It needs the motion permission, and reads the accelerometer only while the app is open.
