A standalone app for Wear OS watches, e.g. Samsung Galaxy Watch 4. Shows the latest glucose reading for a Libre user, with level color and trend arrow. Updated every minute.

The watch app fetches the glucose readings from a server over the Internet, not directly from the sensor. Therefore, the app should not be used for treatment decisions or dosing decisions.

A companion app is installed on your phone, which must be paired with your watch. This is used for entering email and password for the server. These are stored encrypted and sent encrypted from the companion app to the watch.
