## What is Bubble Level?

Ensure Your Surfaces Are Perfectly Horizontal or Vertical with Bubble Level app.

There are four modes that you can choose:
Circle Level: Simultaneously measure the horizontal and vertical angles.
Vertical Level: Ideal for ensuring walls and other vertical surfaces are perfectly vertical.
Horizontal Level: Perfect for checking that tables, floors, and other horizontal surfaces are perfectly horizontal.
Mix Mode: All-in-one display featuring circle, vertical, and horizontal levels.

Lock the Angle:
Need to maintain a specific measurement? Use our "Lock the Angle" feature to freeze the current angle.

Does your phone case or camera bump interfere with the leveling? Our calibration feature allows you to zero out the readings, ensuring you start from a perfectly horizontal or vertical point.

Activate the sound function to receive an audio cue when your surface is perfectly horizontal or vertical. Accuracy has never sounded so good!
