Precise bubble level, spirit level & angle finder with camera, plumb & history.
Need to hang a shelf straight, level a table, or check a wall is perfectly vertical? Bubble Level turns your phone into a precise spirit level, plumb tool, angle meter and angle finder. It uses your phone's own motion sensors, so it works offline, with no setup and no account needed. FOUR MEASURING TOOLS IN ONE APP - Surface level (360°): a bullseye bubble level for tables, floors, worktops and any flat surface. - Horizontal level: a classic spirit level with a bubble vial for shelves, picture frames and rails. - Vertical level: a plumb tool for walls, door frames, posts and cabinets. - Camera angle finder: point the camera at a surface and read its angle live, also useful as a tilt meter. Use the 2-line mode to measure the angle between two edges, such as a corner, a miter cut or a roof pitch. ACCURATE, AND EASY TO READ - Large, clear angle readout in degrees, slope percentage or mm per metre. - Choose 0.1°, 0.01° or 0.001° resolution. - A built-in 2-step calibration removes the phone's own tilt and camera bump error for a true zero. - Hold the reading, set a relative zero, and save it with one tap. - Readings depend on your phone's own sensors; results may vary slightly between devices. LEVEL BY SOUND AND TOUCH - An audible chime, or a Geiger-style tone that speeds up as you reach level, lets you work without looking at the screen. - A haptic click when the surface is level. - Keep-screen-awake mode for long jobs. SAVE, REVIEW AND EXPORT YOUR MEASUREMENTS - Save readings to projects with a name, notes and tolerance grade. - Search and filter your history by project or measuring tool. - Export as a CSV spreadsheet or a PDF report to share with a client or contractor. - Inspection mode: freeze a camera frame, add notes, compare to a blueprint angle and export a photo with the angle overlay (PDF or JPG). SPEAKS YOUR LANGUAGE English, Español, Français, Deutsch, Português, Bahasa Indonesia, Türkçe, हिन्दी, العربية and اردو. Switch language any time in Settings. WHO USES BUBBLE LEVEL - Home DIY: hanging pictures, fitting shelves, checking furniture and appliances. - Carpenters, builders and tilers using it as a carpenter level for floors, walls and worktops. - Photographers and videographers levelling a tripod or camera. - RV, caravan and camper owners parking level. - Anyone who needs a quick slope, tilt or angle reading. TIPS FOR BEST ACCURACY 1. Run the 2-step calibration once on a hard, flat surface. 2. Remove thick phone cases for the most accurate readings. 3. Place the phone's long edge against the surface you are measuring. Your device needs a motion sensor (accelerometer and gyroscope), which most phones have. Camera and location access are optional and used only for the camera tools and the photo location stamp. The app contains ads. Download Bubble Level and get your next project straight, flat and level.
