Level Tool: Spirit Level

About
This app transforms your phone into a precise spirit level and angle finder. It helps you hang frames, install shelves, or mount TVs accurately by indicating tilt to a tenth of a degree. The interface turns green and provides haptic feedback when an object is perfectly level.
What's New in Level Tool
2.0
October 29, 2026
Level Tool 2.0 is rebuilt from the ground up. Bubble reads any edge and Surface reads a flat top, both to a tenth of a degree. The background behind the reading turns green when it's level, and a line tells you which side to raise. Bubble and Surface work without Pro, with no timer. Calibration takes two steps for each tool and allows for your case. Pro adds roof pitch in x/12, slope in percent and a target angle that taps when you hit it. If you bought Pro before, it carries over.
