GonioCam – Goniometer & ROM

Measure joint angles fast

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

GonioCam turns your iPhone into a digital goniometer: take a photo, tap three joint landmarks – and read the joint angle, automatically expressed in neutral-zero notation (e.g. "Knee Ext/Flex 5-0-130"). MEASURE – FREE AND UNLIMITED • Take a photo or import one from your library • Tap three points, fine-tune to the pixel with the loupe • Live angle right on the image, large and readable • Presets for knee, hip, elbow, shoulder (flex/abd), ankle, wrist and generic angles – each with landmark guidance • Hyperextension and deficit notation (0-10-90) handled correctly • Series assessment: several measurements in a row – right side first, then left, with an overview at the end • Share the photo with the angle drawn in (with a “Measured with GonioCam” banner) • Share photos from WhatsApp or Photos straight to GonioCam and measure them DOCUMENT – GonioCam Pro • Create patients (pseudonyms or initials recommended) • Assign measurements: left/right side, AROM/PROM, date • Progress curves across the whole treatment • Left/right side comparison in one chart • PDF report with curves, measurement table and photos – choose exactly what goes in • Unlimited assigned measurements • Share photos without the banner PRIVATE AND OFFLINE No account, no sign-in, no tracking. Photos and measurements stay on your device and are never written to your photo library. METHODOLOGY DISCLOSED The app includes a methodology and accuracy screen: measurement method, evidence on photo goniometry, and our own accuracy check against reference images with known angles. Plus a capture guide with the rules that carry the accuracy. IMPORTANT NOTICE GonioCam is a measurement and documentation tool (digital goniometer) and not an approved or certified medical device. It does not diagnose and gives no treatment recommendations. Clinical judgement remains with the treating professional. PURCHASE OPTIONS Measuring stays free. Unlock the documentation workflow (patients, progress, side comparison, PDF report) in one of three ways: a permanent one-time purchase, a yearly subscription with the first month free, or a monthly subscription. Prices are shown in the App Store. Subscriptions renew automatically for the selected period unless cancelled at least 24 hours before the end of the current period. Payment is charged to the Apple Account and can be cancelled any time in its settings. When a subscription ends, patients, progress charts and the PDF export you already recorded stay readable - only creating new entries is locked.
