Level / Bubble Level

What is Level / Bubble Level?

A digital spirit level that uses your device's orientation sensors to measure tilt. Check whether surfaces are horizontal or vertical — handy for hanging pictures, leveling shelves, or aligning anything without a physical level.

How to use

1. Place your device flat on the surface you want to check — the bubble indicator shows real-time tilt angle in degrees.
2. Rotate your device to portrait mode for vertical leveling — useful for checking door frames and wall edges.
3. Tap the calibrate button on a known-flat surface to zero out any sensor offset for more accurate readings.

Result

You're hanging a shelf and need to verify it's level. Place your phone on the shelf — the bubble reads 1.2 degrees off. Shim the left side until the display reads 0.0 degrees, then secure the brackets.
