Place your phone flat on the bench to measure its incline.
Initializing sensors…
Measures vertical incline only. Spinning the phone flat briefly shifts the reading from motion; it settles at the true angle.
Turn your phone into a free digital inclinometer, or measure any angle on screen with the online protractor. Lay your device flat on a surface to read the incline in real time, or upload an image and rotate the arm to measure angles up to 360° — all in your browser, no app required.
Allow sensor access, lay your phone flat on the surface, and read the incline in degrees. Tap Zero to set a reference or Lock to hold the reading.
On desktop, upload or paste an image, drag the protractor center onto the vertex, then rotate the arm to read the angle up to 360°.
Open this page on your phone, allow motion-sensor access, then lay the phone flat on the surface you want to measure. The incline is shown live in degrees — no app or installation needed.
Yes. Everything runs directly in your browser. On a phone it uses the built-in motion sensors as a digital inclinometer; on a computer it works as an on-screen protractor.
Phone mode measures a surface's incline by placing the device flat against it. Desktop mode lets you measure angles on an image you upload or paste, by rotating the protractor arm from 0° to 360°.
Phone mode reads the incline in real time from the device accelerometer, accurate to within a degree for typical use. Desktop mode snaps to 1° increments so you can align the arm precisely on images.
Yes, ToolHub's angle meter is completely free with no sign-up. You can also use Selective mode to set a target angle and get notified when you reach it.
