Connecting The Libre 2 To A Smart Watch

Home » Connecting The Libre 2 To A Smart Watch

I’ve been used the Libre 1 since it was released in 2014, so when I found out the Libre 2 was being rolled out on prescription in the UK I have been sitting patiently (mostly) until I could get my hands on it. For the last 18 months I have used the MiaoMiao to turn the Libre 1 into a CGM with alarms and, while I was glad to have it available, I couldn’t wait to ditch the extra device and have alarms built in to the Libre 2.

However, I hadn’t realised how reliant I had become on being able to see my blood sugars on my watch. With 2 young kids to chase I really appreciate the ability to glance down and know what my blood sugars are at any given time. At first I didn’t think it was going to be possible with the Libre 2 as I was no longer using the MiaoMiao, but as always seems to be the case with diabetes tech – where there’s a will theres a way!

How To See Libre 2 Readings On A Smart Watch

Accessing your blood glucose readings on a smart watch is actually really simple, and you don’t need any extra devices making it totally FREE. While some people may not see the need to have readings on show 24/7 I know many that really like the idea. During exercise I can glance down at my watch to see what is happening instead of stopping to scan or waiting for an alarm. This lets me deal with a potential issue before it even happens, pre-empting situations and staying 1 step ahead of major blood sugar fluctuations.

Shuggah uses it’s own algorithm to calculate blood glucose readings so it is likely that it will read slight different to your Libre 2. In both cases there may be a delay between what the readings say and what a finger prick says.

Step 1: Install Shuggah

Shuggah is a completely free app, and it is the simplest way of having your blood glucose show on your smart watch. You can download Shuggah from the app store.

Step 2: Disconnect Your Libre 2

Go to your phone settings and switch off the bluetooth settings. You cannot have BG readings on your Apple Watch with the bluetooth on for your Libre 2.

Step 3: Connect To Shuggah

Once you have installed Shuggah go to bluetooth at the bottom of the screen. Press the scan button and wait a few minutes for it to connect. You can then press the home button and see your blood glucose levels.

Step 4: Connect To Your Smart Watch

Each smart watch will have their own individual ways for adding an app to the watch face. I can only speak about an Apple Watch from experience.

For Apple Watch users, you need to have your BG levels appear on your calendar. Use a modular watch face option and place the calendar option wherever you want it. And you’re done!

What To Do If The Libre 2 Keeps Losing Connection

This is usually because you have not turned off the bluetooth for your Libre 2. The Shuggah app has alarms to replace your Libre 2 alarms.

Do You Still Need To Scan The Libre?

If you want to have a full graph on the libre app you will still need to scan your Libre 2 every 8 hours. This will ensure you capture all data.
