Description
Protractor & Angle Finder turns your phone into a two-in-one drafting instrument. Measure angles two ways: with an on-screen protractor you align by hand, or with a sensor inclinometer that reads the real tilt of a surface.
ON-SCREEN PROTRACTOR • A graduated 0-180° protractor dial with fine degree ticks • Two draggable arms — set them to any angle and read the degrees live • Instant complement angle for quick geometry, carpentry and DIY • Reset to a clean 90° base with one tap
SENSOR INCLINOMETER (ANGLE FINDER) • Uses the accelerometer to read the tilt of a real surface • Large degree readout plus slope percentage • Zero-to-surface calibration so you can measure relative angles and bevels • Handy for shelves, ramps, roofs, furniture, camera setups and levelling
BUILT FOR THE JOB • Clean drafting-board layout that stays readable on site • Works fully offline — no account and no internet needed • Switch instantly between protractor and inclinometer modes • Optional haptic feedback when you reach common angles
ABOUT ACCURACY The inclinometer reads your phone's built-in accelerometer, so what you get is as good as that sensor and how flat the phone sits. Use the zero function against a reference surface before an important reading. This is a practical angle measure app for school, workshop and home projects — it is not a calibrated metrology instrument and should not be used where a certified measurement is required.
PRO UPGRADE Unlock Pro to measure angles directly on an imported photo, save and label your measurements, freeze and hold the live reading, and remove ads.
Whether you are a student learning geometry, a carpenter checking a miter, a DIYer hanging a shelf, or a photographer levelling a shot, this digital protractor gives you an angle in seconds.
