GonioCam – Goniometer & ROM

GonioCam turns your Android phone 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 pick one from your gallery
• 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, neck, fingers, big toe 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 your gallery straight to GonioCam and measure them

PRIVATE AND OFFLINE
No account, no sign-in, no tracking. Photos and measurements stay on your device and are never written to your gallery.

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 on Google Play.

Subscriptions renew automatically for the selected period unless cancelled before the end of the current period. Payment is charged to your Google Play account and can be cancelled any time in the Play Store under “Payments & subscriptions”. If you cancel the free month before it ends, you pay nothing. When a subscription ends, patients, progress charts and the PDF export you already recorded stay readable - only creating new entries is locked.
