What you can do

Three ways to take a reading.

Level and plumb

Check a surface or an upright edge against the level display. Use on-device calibration to set up your phone.

Compare angles

Hold a reading or set a reference point so you can measure how far the next angle differs.

Measure from a photo

Trace lines over a photo with the protractor and save readings with notes.
