Clinometer: Level & Angle

Clinometer is the most accurate inclinometer, angle finder, and digital bubble level for Android. Measure tilt, slope, pitch, and angles in seconds — no calibration tools needed.

Whether you're hanging a picture, leveling a deck, mounting a TV, or measuring a roof pitch, Clinometer turns your phone into a professional angle finder you carry everywhere.

▶ MAIN FEATURES

• Inclinometer — single-axis tilt and slope angle in degrees

• Bubble level — dual-axis level for floors, shelves, walls

• Angle finder — measure any angle from 0 to 360°

• Slope meter — show grade in degrees, percent, and ratio (1:N)

• Roof pitch calculator — read pitch instantly

• Hold mode — lock the angle hands-free

• 0.1° precision via accelerometer + gyroscope sensor fusion

• Reference plane calibration — zero on any surface

• Dark mode for outdoor use

• Works fully offline, no account, no ads block

▶ HOW TO USE

1. Open Clinometer and place phone on a flat reference surface for 1-second calibration

2. Hold the phone against any edge, beam, or surface you want to measure

3. Read the angle in degrees, percent grade, or 1:N ratio

4. Tap "Hold" to freeze the value while you adjust the workpiece
