BiPi Bubble Level with Sound

Level surfaces without constantly looking at your screen.

BiPi is a Bubble Level, Spirit Level, and Digital Level with audio guidance that helps you find the perfect level using sound. Inspired by the way radar and metal detectors guide you toward a target, BiPi turns leveling into a simple audio-guided experience.

As you move away from level, the beeps become slower. As you get closer to the target, the beeps become faster. At 0.1°, you will hear rapid beeps. Reach 0.0° and the sound becomes a continuous tone, letting you know that you have locked onto the perfect level.

Audio-Guided Leveling

Keep your eyes on your work instead of constantly checking the screen.

* Slow beeps when you are far from level
* Faster beeps as you approach the target
* Rapid beeps when you are very close
* Continuous tone when you reach 0.0°
* Measure and level using sound

Sound Modes

Choose the audio experience that works best for your task.

* Metal Detector Mode
* Radar Lock Mode
* Stereo Mode
* Silent Mode

Radar Lock Mode gives you a target-style audio experience. The closer you get to level, the faster the beeps become. When you reach 0.0°, the continuous tone tells you that the target has been locked.

Stereo Mode

Stereo Mode adds directional audio guidance to your leveling work.

If the surface is tilted to the left, the sound comes from the left. If it is tilted to the right, the sound comes from the right. This lets you understand which direction to adjust without constantly looking at the screen.

Three Measuring Modes

Choose the measurement that fits your task.

* X Axis Level
* Y Axis Level
* X + Y Combined Level

Use individual axes for simple horizontal or vertical leveling, or use the combined mode when you want to monitor both axes at the same time.

Calibrate for Your Own Reference

BiPi lets you calibrate the level to your current position.

Use calibration when you want to measure from a specific reference angle or treat an existing surface as your new zero point. This makes BiPi useful not only for finding standard level, but also for measuring relative angles and custom reference positions.

Work Mode

Work Mode is designed for hands-on jobs where you need your phone to stay ready while you work.

* Keep the screen on
* Activate the built-in flashlight

Use Work Mode when working in dark areas or when you need continuous access to the level while installing, aligning, or adjusting something.
