Build Level: Bubble & Angle

Turn your smartphone into a full-screen digital bubble level and instantly see the tilt angle in degrees. Place the phone with its long edge against a surface, follow the bubble, and quickly check whether everything is level.

The app is useful for home improvement, installation, furniture assembly, and everyday tasks when a physical spirit level or angle meter is not available.

Main features

• Full-screen bubble level designed for landscape use.

• Digital angle meter with the current tilt shown in degrees.

• Smooth bubble movement and a clear leveling status.

• Two-step calibration for a more accurate zero position on your specific device.

• Reset calibration at any time.

• Light, dark, and system themes.

• Around 250 localizations with language selection in Settings.

• Adaptive interface for smartphones, tablets, and Fold devices.

What you can use it for

• Check whether a shelf, countertop, table, or piece of furniture is level.

• Align a picture frame, wall decoration, or other object during installation.

• Measure the tilt of a board, surface, or structure.

• Quickly check an angle during repairs, furniture assembly, or DIY work.

• Use your smartphone as a digital spirit level when a physical construction level is not nearby.

The interface stays focused on the tool itself. Open the app, place your smartphone horizontally, and use the entire screen as a digital level. If needed, run calibration to compensate for the characteristics of your device body and sensors.
