Bubble Level for Wear OS

Turn your Wear OS watch into a bubble level and tilt meter. Start with Bubble, then switch the view to suit the measurement.

FOUR VIEWS, ONE TOOL
- Bubble: a moving bubble with two-axis tilt readings.
- Precision: a dial, signed angle and slope percentage for your selected axis.
- Horizon: a horizon line with roll and pitch.
- Minimal: a large readout for a quick check.

Set the current position as a zero reference, return to absolute measurement, or hold a reading to view it after moving the watch. Choose the X or Y axis and degrees or percent for the angle readout. A stability indicator helps you see when movement has settled.

Choose a level tolerance of 0.2, 0.5 or 1 degree and enable or disable the level vibration. Five colour themes are available: mint, amber, cyan, lavender and white. Keep the screen awake during a foreground measuring session for 1, 3 or 5 minutes; the screen-awake session ends automatically.

PLACE THE WATCH CAREFULLY
On your wrist, the app measures the watch's tilt. For a surface check, place the watch securely and account for the strap and raised rear sensor. Readings depend on the watch sensors, placement and movement. Display resolution is not a guarantee of measurement accuracy. This is a practical checking tool, not a certified measuring instrument.

Runs offline on the watch without an account or companion phone app. The app interface is in English.

Full screen enlarges the instrument and keeps compact readings in every mode. Tap the display or swipe right to return to the controls. The screen-awake default is one minute.
