Frequently asked questions
How accurate is a phone as a level?
Good enough for hanging pictures and shelves, but not for precision work. Calibrate on a flat surface first and take the reading from the same edge each time.
Why does the level not respond?
The page needs a device with motion sensors and permission to use them. Desktop computers usually have none, so open the tool on a phone.
How can I check it is calibrated?
Place the phone on a surface, note the reading, turn it 180 degrees and compare. If the two readings differ, the sensor is off a little.
