If you’re using the FreeStyle LibreLink app, your sensor can only store data for up to 8 hours.

If you wait longer than this, your sensor will start to replace the earliest data in its memory with new data. This can lead to gaps in your glucose graphs and missing data.

For example, if you go 9 hours between scans, you will see a 1-hour gap at the beginning of that 9-hour window, because the sensor can only remember the most recent 8 hours.

We’d recommend scanning your sensor:

  1. Just before you go to bed at night

  2. First thing when you wake up in the morning

  3. Once or twice during the day at a minimum (set an alarm if you could use a reminder)
