About

Goniometer

Features
Read full description

Goniometer turns your smartphone into a joint range-of-motion measuring tool, designed for physiotherapists and healthcare professionals. Using the device's inertial sensor (IMU), measure the angle of a movement in real time, set the zero in the starting position, then capture the left and right sides to compare. An asymmetry of 10° or more is flagged automatically. Three ways to measure • Motion sensor (IMU) — lay the phone against the segment and the angle updates live, with its trace. • Angle dial — a large, clear, centred reading. • On a photo — place three points (segment, joint, segment) and the angle is computed automatically. Highlights • Real-time measurement and set-to-zero (tare) • Left / right comparison and asymmetry detection (≄ 10°) • Angle movement trace • Goniometric measurement on a photo • Built-in step-by-step help and FAQ • Available in English, French, German, Spanish, Italian, Dutch, Polish, Greek and Portuguese Goniometer is part of Physia, the clinical software ecosystem developed by Procaryote: rigorous, easy-to-use, privacy-first tools to assess, measure and follow up your patients. Goniometer is a measurement-aid tool for healthcare professionals; it does not replace clinical judgement or a certified medical device.
