What is Level / Bubble Level?
A digital spirit level that uses your device's orientation sensors to detect tilt and help you check if surfaces are perfectly horizontal or vertical. Ideal for hanging pictures, leveling shelves, or any task that requires precise alignment without carrying a physical level.
How to use
- Place your device flat on the surface you want to check — the bubble indicator shows real-time tilt angle in degrees.
- Rotate your device to portrait mode for vertical leveling — useful for checking door frames and wall edges.
- 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.
