Get Started Scanning
In order to retrieve all the data from your CGM, you will need to scan it at least once every 8 hours. The CGM records up to 8 hours of data, so in order to get a full 24 hours of data in a day you will need to scan the sensor a minimum of 3 times throughout the day, every 8 hours. You can scan more often if you would like, however, if you scan less than every 8 hours you will see gaps in the data.
To get data from the CGM device into the app you will need to scan it:
1. Tap the green "+" from the dashboard screen
2. From the popup screen, tap the "Scan" circle icon
3. A "Ready to Scan" prompt will appear.
4. Once you see the prompt, place the area of the phone with the NFC near the CGM device and hold it there for a second.
You should feel a vibration once the sensor has been scanned. For iPhones, the NFC is located on the front of the phone, near the front camera. For androids, the NFC location varies but will be on the back of the phone.

Want to Scan Quicker?
For iPhones, utilize the widget feature. Hold down on the Nutrisense app for a quick option to scan, log a meal or activity, or ask us a question!
For Androids, try scanning without opening the scan dialogue. Open the dashboard view and touch your phone (wherever the NFC is located) to the sensor and it will scan automatically.
How Often Should You Scan
The readings are recorded in 15-minute increments and the device will capture the last 8 hours of data. This means that you have to scan the device a minimum of every 8 hours to cover the entire 24 hour period. We recommend scanning before going to bed and upon waking up, in order to capture as much of the night data as possible.
