About this app

Wear OS app that shows glucose values from Dexcom Share or LibreLinkUp

Can also work separately as Tile and/or Complication in other watch faces.

Note! Only useful for people who are using a Dexcom CGM, and has blood sugar data uploaded to Dexcom Share or LibreLinkUp.

Note! Wear OS v5 does no longer allow apps to also have a watch face, so the watch face is not included in Wear OS 5. It's only included for Wear OS v4 and v5.

The watch face can show:

* Current glucose value in mmol/L or mg/dL
* Trend
* Graph
* Battery level
* Glucose target range
* Difference between values as bars

Double tap on the watch face to get to a details view
that shows average glucose during last 24h,
current stats, such as for how long the glucose
has been in range / above / below.

You can also access glucose graphs for 6h, 12h and 24h, and configuration from this view.

Optional vibrations can be configured for when glucose gets too high, or too low. NOTE! vibrations are just a best effort, you should still use the alarms in the official Dexcom app. Your watch might enter sleep mode, and the network connection could be down, and you won't get any vibrations in those cases.

Do note that this Watch Face doesn't require an app on the phone, but it requires access to a web browser during initial configuration, when entering Dexcom credentials.

Blose shouldn't be used instead of CGM providers official apps.

Note that there can be short delay between the CGM sending a value to sharing servers, and Blose receiving it.

The credentials are only stored on your watch, and in an encrypted format, and everything will be removed when the app is uninstalled. The credentials will only be used to login towards CGM providers sharing servers, and won't be shared with anyone.

The app does not contain any advertisement, and doesn't track, or share any data.

For Dexcom:

IMPORTANT! Dexcom share might not work for users that have phone numbers as user id. Prefixing the phone number with country code can work. This is not a bug in Blose, but a limitation in the Dexcom API.

Important note if you don't get any glucose readings!
Blose is downloading glucose readings from Dexcom Share, so sharing must be turned on in the Dexcom main app, and it might require that you have at least have one follower. You can download Dexcom follow on your phone, and invite yourself, then delete the Dexcom follow app when you start getting readings, but keep the follower invited in the main app.

For LibreLinkUp:
Blose will only automatically fetch a value every 5th minute, in order to not drain the battery. Single tap on the watch face can at any time force a download of most recent value.
Libre users that don't have a follower should create a LibreLinkUp account, and invite that user. Use the LibreLinkUp credentials when logging in in Blose.
Blose will follow the first user, if the LibreLinkUp account is following more than one user.
Note! Libre 2 in US doesn't upload values continiously, so Blose works best with Libre 3 in US. Both Libre 2 and 3 should work in Europe.

Ratings and reviews

The app, in general, is nice. The watch face is uncomplicated, easy to see & understand. Alarms can be disabled, & changed from audible to vibrate. The big problem for me, is that the vibrate doesn't persist until silenced. It buzzes one short pattern and stops. I bought a smart watch to wake me silently so my wife's sleep is undisturbed. If the vibrate doesn't wake me, it's useless. I previously used Libre 3 & Juggluco, & that would just keep buzzing till I pushed a button which was much better

I used to like it then all of a sudden it stopped working. my dexcom g7 user name is my phone number and I've see a lot of other reviews of this not working all of a sudden when it used to work just fine for months and months.

Used to love this invaluable app, however its stopped working a few days ago on Xiaomi Watch Pro 2 using Dexcom G6. Think it may be something to do with Wear OS 5? Hope the developers can sort this problems out? *update!* 5/11/2025 when I run the app on my watch states it needs permissions & these can be changed on the next step, when OK is pressed it just says alarms & reminders scrolling and nothing else? Logs state "missing exact alarm permission" please help
