About

Bubble Level!

Read full description

A bubble level, spirit level, or simply a spirit is easy to use, stylish & accurate. It is a tool designed to indicate whether a surface is horizontal (level) or vertical (plumb). The Bubble Level app is accurate, simple to use, and an incredibly useful tool. Hold any of the phone's four sides against an object to test it for level or plumb, or lay it down on a flat surface for a 360° level. The Bubble Level app tries to imitate the real bubble or spirit level and displays the phone’s data as a real level would. Features: - Horizontal & vertical level tool - Manual calibration & reset functions - Dark mode & light mode - Bubble level & bull's eye level 17 Languages: - English - Ukrainian - Arabic - Catalan - Dutch - Estonian - French - German - Italian - Japanese - Korean - Chinese - Polish - Portuguese - Romanian - Spanish - Turkish
