## What is GonioCam?

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
• Automatic point suggestion for knee, hip and elbow – your confirmation is always required
• Share the photo with the angle drawn in

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

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. Pose detection also runs entirely on device.

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.

## Version history (last 3 releases)

### 1.2 — 2026-08-27

GonioCam Pro now comes three ways: as the permanent one-time purchase as before, as a yearly subscription with the first month free, or as a monthly subscription. That way you can try the documentation workflow first instead of paying a lot up front. Important: when a subscription ends, the patients, progress charts and PDF export you already recorded stay readable and exportable — only creating new entries is locked. Measuring stays free and unlimited for everyone.

### 1.1 — 2026-08-15

New: you now choose joint and movement before taking the photo, so the capture rule is in the viewfinder while you frame the shot. Each movement is shown with a pictogram of its direction. Patients can have an optional identifying picture; without one you now see initials instead of the same figure for everyone. The picture stays on your device and never appears in the PDF report. Also: GonioCam is now a universal app and runs on iPad, with the patient list next to the record.

### 1.0 — 2026-08-13

No release notes.
