GonioCam for Android

Home·Apps·GonioCam·Android

GonioCam is also available for Android, with the same features and prices as the iPhone app. How the neutral zero method works, why every joint has its own zero point and how accurate a photo measurement is, is explained in detail on the app's main page — this page is about the Android version.

Measuring — free and unlimited

• Take a photo or pick one from your gallery — including a picture someone sends you on WhatsApp: use “Share” to send it straight to GonioCam.
• Tap three points and fine-tune them with the loupe; the angle appears live and large on the image.
• Eight templates: knee, hip, elbow, shoulder (flexion and abduction), ankle, wrist and a generic angle — each with the landmarks to tap.
• Neutral zero notation automatically, including hyperextension and deficit (0-10-90).
• Series assessment: several measurements in a row, right side first, then left, with all values in an overview at the end.
• Share the photo with the angle drawn in, with a “Measured with GonioCam” banner.

Documenting with GonioCam Pro

• Create patients and assign measurements: left or right side, AROM or PROM, date.
• Progress charts across the whole course of treatment.
• Side comparison of left and right in the same chart.
• PDF report with charts, a measurement table and photos — you choose what goes in.
• Unlimited assigned measurements, and photos shared without the banner.

Pricing

Measuring stays free. GonioCam Pro is available on Google Play in three ways: a one-time purchase for €19.99, a yearly subscription for €9.99 with the first month free, or a monthly subscription for €2.99 (prices in Germany; they may differ in other countries).

Subscriptions renew automatically for the selected period unless canceled before it ends. Payment is charged to your Google Play account, and you can cancel 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, the patients, progress charts and PDF export you already have stay readable — only creating new entries is locked.

Requirements

The app runs on Android 8.0 or later on phones and tablets; on a tablet, navigation sits in a sidebar. It is available in seven languages: English, German, French, Spanish, Italian, Dutch and Brazilian Portuguese. When a newer version is out, the app tells you; updates come through Google Play.

The app also includes a capture guide with the rules for accurate photos and a “Methodology & accuracy” screen covering the measurement method, published evidence and our own accuracy check against reference images.
