Bubble Level

Turn your smartphone into a precise bubble level using the built-in accelerometer sensor. Whether you're hanging a picture, leveling a shelf, or checking a surface — Bubble Level gives you an accurate, easy-to-read spirit level right in your pocket.

★ SURFACE MODE

Place your phone flat on any surface. A 2D bubble shows tilt in all directions with precision guides and crosshairs. See exactly how far off level you are.

★ EDGE MODE

Stand your phone on its edge against a wall, frame, or any vertical surface. A horizontal bar shows precise left-right tilt alignment — perfect for hanging pictures and mirrors.

★ REAL-TIME ANGLE DISPLAY

Large, easy-to-read degree readout updates instantly. Color-coded feedback: green when level, yellow when close, red when tilted.

★ COLOR FILL VISUALIZATION

Full-screen color fill rotates with your device, making it easy to see tilt direction even from a distance. Great for hands-free positioning.

★ HAPTIC FEEDBACK

Feel a gentle vibration when the surface is perfectly level. No need to watch the screen — just feel when it's right.

★ LOCK & CALIBRATE

Lock the current reading to compare later. Calibrate the sensor to zero on any surface for precise relative measurements.

★ PORTRAIT & LANDSCAPE

Works in both orientations. The layout adapts automatically with correct axis mapping for accurate readings in any position.

★ DARK & LIGHT THEMES

Choose your preferred theme or let the app follow your system settings.
