Bubble Level – Bubble & Angle

Bubble Level is a free spirit level and angle meter app that turns your phone into a precise measuring tool. Whether you need a simple bubble level, a 2D level for two-axis leveling, or an angle meter for slopes and edges, this app gives you fast, accurate readings using your phone's built-in sensors, with no extra hardware required.

FIND YOUR LEVEL, INSTANTLY

Open the app and start measuring right away. The bubble level shows a live reading with clear visual feedback, so you always know when a surface is perfectly level. Use the classic bubble level for shelves, picture frames, and tables, or switch to 2D level mode to check tilt on both axes at once, perfect for tiles, countertops, and furniture.

ANGLE METER FOR SLOPES AND EDGES

Need to measure an angle instead of a flat surface? The built-in angle meter, also called a protractor mode, measures angles from 0 to 180 degrees. Place your phone against a slope, ramp, or edge to get an instant angle reading. This makes the app useful as a slope meter and tilt meter for construction, woodworking, and DIY projects.

CAMERA LEVEL FOR STRAIGHT PHOTOS

The camera level mode overlays a crosshair guide on your live camera view, helping you keep horizons straight while you frame a photo. It is a simple way to combine a bubble level with your camera for architecture, landscape, and interior photography.

MULTIPLE UNITS, YOUR CHOICE

Read your angle in degrees, percent grade, or millimeters per meter. Switching units takes one tap, so the level app fits carpenters, installers, hobbyists, and anyone who just needs a quick level check at home.

SAVE AND REVIEW YOUR MEASUREMENTS

Every measurement from the bubble level, 2D level, or angle meter can be saved to your history, so you can check past results without measuring again. Calibrate the zero point at any time for extra accuracy on any surface.
