How to make the most out of Veri in terms of scanning

The FreeStyle Libre 1 sensor must be scanned at least once every 8 hours to manually transfer the data from the CGM to the app software.

Since the sensor's memory only lasts 8 hours, if you go longer than 8 hours then the oldest data collected by the CGM will be erased and replaced with the newest data. This will result in data loss and a gap in your Veri glucose graph. For example, if you scan at 10pm and then the next morning at 8am, you'll lose the data between 10pm - 12am.

To avoid data loss we recommend scanning:

  • When you first wake up

  • Once in the afternoon

  • Once in the early evening

  • Once right before bed.

You'll use the LibreLink app to scan the sensor and the data will be transmitted across to Veri by our sync feature. The data will only transfer if your phone has wifi or a cellular data connection.

If you are traveling and do not have cellular service, continue scanning with the LibreLink and all the data will come to Veri once you have a data connection.

There is no maximum limit to how often you want to scan! Your meal scores will be ready 2.5 hours after logging the meal, and you can set the app to send you a reminder when your meal score is ready.

The FreeStyle Libre 2 sensor within the US also requires manual scans once every 8 hours.

Scanning is not necessary for the FreeStyle Libre 2 sensor in the UK/ EU as the Libre 2 sensors in Europe and the UK are Bluetooth enabled, so your glucose data should transfer automatically from your sensor to the LibreLink app.

*Amongst the Veri team, we have found that manual scanning is still required about 30 - 50% of the time, however.

The Libre 3 sensor across regions does not require scanning due to Bluetooth compatibility. You will only need to scan the sensor to begin the 1-hour calibration process at the beginning of the sensor's 14-day lifespan. Then, simply keep the Freestyle Libre 3 app open in the background of your phone and each time you open the Veri app, the glucose data will automatically populate.
