About this app

Turn your smartphone into a practical bubble level, spirit level and digital inclinometer. Bubble Level helps you check horizontal and vertical surfaces, measure tilt angles and estimate slopes using your phone's built-in motion sensors.

Whether you're hanging a picture, installing a shelf, checking furniture alignment or working on a DIY project, Bubble Level puts useful measurement tools right in your pocket.

KEY FEATURES

• Real-Time Bubble Level
Watch the digital bubble move as you tilt your phone. Check whether a surface is horizontal or vertical with responsive visual feedback.

• Circular Spirit Level
Use the round bubble level to check flat surfaces in two directions at once. The clear crosshair and green bubble make alignment easy to follow.

• Horizontal & Vertical Level
Use dedicated level indicators to check edges, walls, shelves, tables and other surfaces.

• Digital Inclinometer
Measure tilt angles in degrees using your device's built-in sensors. Read X and Y angles directly on the screen.

• Slope Measurement
View slope information as a percentage, useful for checking inclines, ramps and other angled surfaces.

• Camera Inclinometer
Use your phone's camera with visual alignment guides to examine angles and reference lines in your surroundings.

• One-Tap Calibration
Calibrate the digital level against a known reference surface to adjust the zero position.

• Measurement Lock
Freeze the current reading when you need to check or record an angle.

• Measurement History
Save measurements for later reference and export your recorded values when needed.

• Ruler & Protractor
Access additional measuring tools, including a digital ruler and an interactive protractor.

• Sound & Vibration Feedback
Receive optional feedback when the measured surface approaches the selected level position.

• Clean, Easy-to-Read Interface
A dark interface with bright green indicators, large angle readings and straightforward controls.

PRACTICAL EVERYDAY USES

Bubble Level is useful for many household, workshop and DIY tasks:

• Hanging picture frames and wall decorations
• Aligning shelves and cabinets
• Checking tables and furniture
• Measuring surface inclination
• Checking horizontal and vertical alignment
• Examining slopes and tilt angles
• Supporting woodworking and home improvement projects

HOW TO USE BUBBLE LEVEL

1. Open the app and choose your measuring tool.
2. Place your phone against or on the surface you want to check.
3. Watch the bubble and read the displayed angle.
4. Calibrate using a known level surface when necessary.
5. Lock or save the measurement for future reference.

BUILT FOR REAL-WORLD MEASUREMENTS

Bubble Level uses compatible Android motion sensors to calculate device orientation and display angle readings. Measurements depend on your phone's sensors, calibration and physical positioning.

For better results, use a stable surface, allow readings to settle and calibrate against a reliable reference.

The app is intended for everyday alignment and measurement assistance. It is not a substitute for certified professional measuring equipment when verified accuracy is required.

Install Bubble Level and keep a convenient spirit level, angle meter and inclinometer available whenever you need them.
