## Description

Turn your phone into a bubble level.<br><br>Bubble Level uses your device&#39;s built-in accelerometer to check whether a surface is flat, an edge is straight or something sits at the angle you need. Measuring works without an internet connection.<br><br>WHAT YOU CAN DO<br><br>• Check horizontal surfaces — tables, shelves, floors, appliances<br>• Check edges and vertical surfaces — shelves, picture frames, walls, door frames<br>• Hang pictures, mirrors and TV mounts straight<br>• Read the tilt angle in degrees<br>• Freeze the reading when the screen is hard to see<br>• Calibrate on a flat surface for better accuracy<br><br>TWO MODES<br><br>• Surface: lay the phone flat. A two-axis bubble shows the X and Y angles and the total tilt<br>• Edge: hold the phone upright against a shelf, frame or wall and read a single angle<br><br>FEATURES<br><br>• Readings in degrees<br>• One-tap Calibrate, and Reset calibration whenever you like<br>• Hold: freeze the current reading<br>• A beep when the phone reaches level, with an on/off button<br>• Dark and light theme, following your system setting<br>• The screen stays on while you measure<br>• Correct readings on tablets in landscape too<br>• Available in 14 languages<br>• Measuring works offline<br><br>ACCURACY<br><br>The app reads your device&#39;s accelerometer directly. For the most reliable result, place your phone on a surface you know is flat and run the calibration once. The calibration is stored on this device only: sensors differ from phone to phone, so it is not moved to a new phone with your backup. Calibrate again on a new device. Accuracy depends on your device&#39;s sensor quality, so this app is intended for everyday household and DIY use rather than professional engineering measurement.<br><br>ADS AND PERMISSIONS<br><br>This app is free and supported by a single banner ad at the bottom of the screen. The ad never covers the level or the buttons. Showing ads requires an internet connection; measuring does not.<br><br>The app does not access your camera, microphone, precise location, contacts, photos or files. Motion sensors do not require a runtime permission on Android.<br><br>Whether you are hanging a shelf, levelling a washing machine or setting up furniture, Bubble Level gives you a quick answer without digging out a physical tool.
