Sibionics GS3 in Australia: buy it on its own or with Vively?

The Sibionics GS3 is a continuous glucose monitor (CGM) you wear on the back of your arm for up to 14 days. In Australia you can buy it on its own from Air Liquide Healthcare, from $89 a sensor on subscription, or as part of Vively's CGM program, from $124.75 a sensor, which adds the Vively app and program. It is the same sensor either way. What changes is the app you read it in and the help you get to act on your results.

What is the Sibionics GS3?

The GS3 is a small, round sensor made by Sibionics. You apply it to the back of your upper arm with an applicator, and a thin filament sits just under your skin. It reads your glucose every 5 minutes, sends the readings to an app on your phone and lasts up to 14 days.

It is factory calibrated, so you do not need finger-prick tests to set it up. It is water resistant, so you can shower, exercise and swim with it on. Our guide to continuous glucose monitors explains how CGMs work and compares the other sensors sold in Australia.

Sibionics lists Air Liquide Healthcare as its official partner in Australia. Vively also supplies the GS3 as part of its CGM program.

GS3 on its own or with Vively: what's the difference?

What Vively adds to the GS3

The sensor is the same, so the difference is what you get around it. Vively's CGM program is built for people without diabetes who want to understand how food, sleep, activity and stress affect their glucose, and what to change.

• A range that suits you. The Vively app shows your readings against 4 to 6 mmol/L, rather than a range set for diabetes care.
• Your meals, sleep and exercise in one place. Log them in the app and see how each one lines up with your glucose.
• Your blood test results next to your glucose. Results from a Baseline Health Check sit in the same app.
• Dietitian coaching. It is available when you upgrade to the $99 a month Vively membership.
• No prescription needed. You can order online.

Is it worth paying more?

A GS3 bought on its own costs $99, or $89 on subscription. Vively's single-sensor pack costs $199, and the 4-pack brings it down to $124.75 a sensor. The extra pays for the Vively app and program. If you only want the hardware and plan to read the numbers yourself, buying the sensor on its own is cheaper. If you want help turning your readings into changes, the program is the better fit. Our CGM cost guide compares every CGM sold in Australia.

Things to check before you buy

• Your phone. Check that your phone model works with the app you plan to use.
• Cost over time. One sensor covers 14 days, so a month of readings needs 2 sensors.
• NDSS. The GS3 is not subsidised on the NDSS, so everyone pays privately.
• The instructions. Read the instructions that come with the sensor. Air Liquide's product page sets out the GS3's intended use.
• Your health. If you have diabetes, talk to your treating team before you change how you monitor. If a reading does not match how you feel, follow the sensor instructions and check with a finger prick.
