PLEASE READ THIS ADVISORY

Never make a medical decision based on a reading that you see on this app. Always perform a fingerstick blood glucose check first.

IMPORTANT: Due to a bug in Garmin's Connect app (since mid July 2025), HTTP communication requests are blocked after a certain time. In case you don't receive CGM data (but have before), please synchronize your watch with Connect (not ConnectIQ). This should get things working, again.


INSTALL COMPANION APP OR USE NIGHTSCOUT

For easiest use, install xDrip+ on your Android phone
https://xdrip.readthedocs.io/en/latest/install/download/

To enable communications between our app and the Android app xDrip+, you have to enable "xDrip Web Service" (xDrip Settings - Inter-app settings).

If you are stuck with IOS or prefer to use Nightscout, please enter URL of your Nightscout website with leading https:// and provide a security token in the settings.

Due to limitations in Garmin SDK, query of CGM data can not be more often than once every 5 minutes, therefore it may take up to 15 min for initial sync.

If you encounter problems to receive data from Nightscout or xDrip please try the following steps:

1. Make sure to put in the correct URL and corresponding token if you want to connect to Nightscout. Leave these lines blank if you are using xDrip+.

2. Make sure there are no leading or trailing white-spaces or slashes (/) on your URL or token.

3. To investigate HTTP request issues, activate "Debug Web-Request" in the settings (via Connect IQ app). You can observe the URL and token used by the app on the watch itself. Either a success or error message will be shown.

4. The watch face needs to poll the data after it is processed by xDrip or uploaded to Nightscout. A standard delay of 10 seconds is used to accomplish this. You can adopt this value to your setup needs by changing the "Web-Request latency" in the settings (via Connect IQ App). If CGM readings always arrive late (delay grater than 5 minutes), try to increase latency. Values between 1s and 120s are valid.
