Bubble Level – Angle Meter

Bubble Level turns your phone into a handy, precise measuring tool. Use it to hang shelves and pictures, set up furniture or check the slope of any surface. ★ TWO MEASURING MODES • Horizontal mode: lay the phone flat and the circular bubble shows level on both axes at once. • Vertical mode: stand the phone on its edge to check walls, doors and posts. ★ CLEAR ANGLE READOUT • X and Y angles with 0.1° resolution • The bubble and readings turn green when the surface is level (within 0.5°) ★ SOUND AND VIBRATION • A beep when you reach level • Optional vibration, so you can feel level without looking at the screen ★ CALIBRATION • A 3-second countdown, then several readings are averaged • Reset the calibration at any time ★ HOLD • Freeze the reading where you can't see the screen and read it later ★ AR CAMERA • Level overlay on the camera view to align against real objects ★ EASY TO USE • Works in portrait and landscape • The screen stays on while measuring • English and Turkish • Works on small screens and with large font sizes Camera permission is only requested for AR mode. Note: Accuracy depends on your device's sensor. For best results, calibrate on a flat surface the first time you use the app.
