Guardian Monitor is an iPhone app developed by Kacper Rychlinski. It falls under the category of Education & Reference, specifically in the field of Medicine. This free app is designed to read glucose values from one of the available CGM services without making any changes to the settings.

To use Guardian Monitor, you will need to have your own account with the original CGM service as authorization is required for the app to function properly.

One of the standout features of Guardian Monitor is its alarm mechanism. Users can configure the app to set alarms for reaching and predicting glucose limits, as well as for cases when no readings are received from the CGM service. This added functionality extends beyond the standard features offered by the original service.

The app also offers glycemic and statistics charts, the ability to turn on snooze for alarms, Apple Watch support, and a widget extension that displays a chart and the last glucose value.
