Spirit level, clinometer & angle finder with bullseye view and calibration.
Bubble Level Tool turns your Android phone into a practical digital level for checking alignment, tilt, inclination, and surface balance. Use it as a bubble level, spirit level, clinometer, inclinometer, angle finder, and surface level for DIY, furniture setup, shelves, appliances, carpentry, and everyday measurements. Measure horizontal and vertical alignment, check surface balance with the bullseye view, track inclination with the built-in clinometer, set target angles, and calibrate your device for more consistent readings. BUBBLE LEVEL & SPIRIT LEVEL Use your phone as an easy-to-read bubble level for checking whether a surface is straight, flat, horizontal, or vertical. The level screen shows clear angle readings for both axes. Useful for: • Hanging pictures and frames • Installing shelves • Leveling tables and furniture • Checking refrigerators and washing machines • Aligning cabinets and countertops • Setting up tripods and equipment • DIY, carpentry, and home improvement BULLSEYE LEVEL Use the Bullseye View to check surface balance across the X and Y axes at the same time. Place your device flat on a surface and watch the bubble move toward the center while viewing separate angle readings for each axis. Use it as a surface level for tables, desks, appliances, workbenches, equipment, and furniture. CLINOMETER & INCLINOMETER Measure tilt and inclination with the built-in clinometer. The large digital angle display makes the app useful as an inclinometer, angle meter, tilt meter, slope meter, and angle finder. Use it for: • Surface angles • Tilt and slope • Inclined objects • Equipment positioning • DIY measurements • Construction angles • Tripod and camera setup SET & LOCK TARGET ANGLES Set common target angles such as 15°, 30°, 45°, 60°, and 90° for faster repeated alignment tasks. Target angles are useful for woodworking, installations, equipment positioning, angled surfaces, and DIY projects. You can also lock a reading to keep the measurement visible while making adjustments. CALIBRATION Different phones use different motion sensors, and cases or camera bumps can affect how your device rests against a surface. The built-in calibration tool guides you through a simple process: • Place your phone on a known flat surface • Keep the device steady • Confirm and save calibration You can reset calibration whenever needed. SMART MEASUREMENT CONTROLS Customize how Bubble Level Tool behaves while you work: • Sound when the surface reaches level • Adjustable sound volume • Vibration when level is reached • Adjustable vibration duration • Custom level threshold • Auto-freeze when a reading becomes stable • Adjustable sensor sensitivity • Angle unit settings DISPLAY & EXTRA TOOLS Make the app easier to use in different environments with: • Keep screen on while measuring • High-contrast mode • Theme controls • Measurement history • Auto-freeze stable readings Measurement history lets you review saved readings when you need to compare or reference earlier measurements. ONE APP, MULTIPLE LEVEL TOOLS Bubble Level Tool combines useful measuring functions in one place: Bubble level Spirit level Digital level Leveler Bullseye level Surface level Clinometer Inclinometer Angle finder Angle meter Tilt meter Slope measurement Horizontal level Vertical level Use it for home improvement, DIY work, woodworking, carpentry, furniture assembly, appliance leveling, photography, equipment setup, shelf installation, picture hanging, and general surface alignment. Measurement accuracy depends on the sensors available in your Android device. For professional, structural, engineering, or safety-critical work, verify important measurements with appropriate professional equipment. Install Bubble Level Tool and keep a digital spirit level, bullseye level, clinometer, inclinometer, and angle finder ready whenever you need to measure level, tilt, slope, or alignment.
