The Bubble Level & Ruler is an incredibly useful portable tool that we provide on smartphones, offering three types of level tools: horizontal, vertical, and planar bubble levels. It displays the current tilt angle of your phone in real-time and can be calibrated at any time.

At the same time, we also offer rulers with both centimeters and inches, allowing you to measure actual distances using your smartphone.

By effectively combining the bubble level and ruler, you can easily complete various complex combination measurements, such as hanging pictures, checking if a table is level, determining nail positions, and many other common household tasks. It's very practical.

The Bubble level tool is free to use forever. Download and try it out now!
