Opened to a game that couldn't be stopped. Eventually got to the level screen. Found that the calibrate button didn't calibrate anything, merely set the indicator to read zero. So, it will show how many degrees one surface is from another, but not if it is level. Waste of time, look elsewhere.

Great level app

Beats fo days

This app works well, especially if you recalibrate it before you measure. Great app.

Too many ads!!


If you could use the app for more than 5 seconds without an ad taking over I would maybe give it a higher rating. Don't waste you time with this one.
