Bubble Level - Digital Level

Bubble Level: Digital Level is a simple bubble level app that turns your Android phone into a handy digital spirit level and angle measurement tool. Check horizontal surfaces, align upright objects, and view phone tilt for everyday DIY and home tasks.

A DIGITAL BUBBLE LEVEL
Use your phone as a digital level, spirit level, or level meter. An accelerometer shows live tilt readings and a moving bubble.

HORIZONTAL LEVEL
Place your phone on a flat surface to check horizontal alignment. The tubular bubble moves across the X-axis to help check tables, shelves, countertops, and appliances.

VERTICAL LEVEL
Hold your phone against an upright surface to check vertical alignment. Use it to position picture frames, wall decorations, cabinets, doors, and shelves.

CIRCULAR BULLSEYE LEVEL
Check tilt in different directions at the same time. Its center bubble and guide rings show your phone's position on tables, countertops, platforms, and tripods.

LIVE TILT AND ANGLE MEASUREMENT
See X-axis and Y-axis readings as you move your phone. Check inclination and slope direction with this digital inclinometer, tilt meter, and angle measurement tool.

CALIBRATE YOUR LEVEL
Tap Calibrate to set the current position as your reference point. Set a relative zero point for the position you are checking.

LOCK AND RESET
Lock freezes readings, Unlock resumes live values, and Reset restores the original calibration reference.

DIGITAL RULER AND ON-SCREEN CALIPER
Measure a distance across your phone display with the built-in on-screen ruler. Move the two guides independently to mark the points you want to measure. Touch and position the guides with subdivision snapping. Read the live distance and switch between centimeters (cm) and inches (in). This is an on-screen ruler, not a camera tape measure.

SOUND LEVEL INDICATOR
Turn sound feedback on or off in Settings. A short beep alerts you when the reading enters the level range; it does not play continuously.

LIGHT MODE AND DARK MODE
Choose Light Mode with silver and green accents or Dark Mode with charcoal and bright green accents.

USEFUL FOR HOME AND DIY
A phone bubble level can help when:
• Checking a shelf, table, or countertop
• Aligning a picture frame or wall decoration
• Positioning furniture and household appliances
• Checking a wall, cabinet, or door frame
• Setting up a platform or tripod
• Checking the tilt of a surface
• Taking a quick on-screen measurement with the ruler

SIMPLE CONTROLS
Place or hold your phone against a surface and read the bubble and angle values. Calibrate, lock, or reset as needed. The screen stays awake during use.
