Description
The motivation to write Juggluco was the need to use the sensor glucose values for something more than knowing my current glucose level or getting a global view the success of my glucose control. I wanted to use the glucose curve to easily refer back to previous experiences and see exactly how it went in relation to insulin doses, carbohydrate intake and activities. A little isolated slowly generated curve in portrait mode doesn’t allow for that. Juggluco is an app that receives glucose values via Bluetooth from Freestyle Libre 2, 2+, 3 and 3+, Sibionics GS1Sb, Dexcom G7/ONE+, Accu-Chek SmartGuide, CareSens Air and Linx/Aidex X sensors. In addition, Juggluco can scan NovoPen® 6 and NovoPen Echo® Plus and receive test results via Bluetooth from Contour Next glucose meters. Juggluco can send glucose values to all kinds of smartwatches, see left menu→Watch→Help: https://www.juggluco.nl/Jugglucohelp/watchinfo.html The phone version of Juggluco can talk out incoming glucose values, display it in a widget on the home screen and in floating glucose above other apps. Juggluco can display the usual glucose statistics. Other apps can receive data from Juggluco via glucose broadcasts and the web server in Juggluco. Juggluco can send data to Health Connect, Libreview and Nightscout. Data can also be exported to a file or send to another exemplar of Juggluco on another phone, tablet, emulator or watch. It has the option to set low and high glucose alarms and medication reminders. StartTo use a Libre 2 sensor, scan it with Juggluco. To take over a Libre 3 sensor from Abbott's Libre 3-only app, you need to enter in left menu→Settings→Exchange data→Libreview the same account as when activating the sensor and press Get account ID, to receive a number from Libreview. When you now scan the sensor this number will be sent to the sensor. No Libreview account is needed, when the Libre 3 sensor is activated with Juggluco: enter an arbitrary number before scanning the sensor. The first time it takes 2 to 10 minutes before Juggluco receives a glucose value via Bluetooth from the sensor. To prevent interference, force stop apps and turn off devices previously used with the sensor. To keep Juggluco running in the background, allow background activity and turn off battery optimizations for Juggluco. Don’t hide Juggluco’s notification. After scanning a Libre 2 sensor with Juggluco, Abbott’s Libre 2 app can only scan the sensor (when two apps are on the same phone they can both receive glucose values from European Libre 2 sensors, but this can give connection problems.) Libre 3 sensors can still be used with Abbott’s Libre 3 only app after using it with Juggluco: stop Juggluco and scan the sensor with Abbott’s Libre 3 app, agreeing that you stop the current sensor and start a new one. When going back to Juggluco you have to scan again. Scan with left menu→Photo the data matrix on the applicator for of Dexcom G7/ONE+, the package of Sibionics GS1Sb and Linx/Aidex X and the inner package of CareSens Air, and the blue cap of Accu-Check SmartGuide sensors. For the last enter the pin when asked. Warning: CareSens Air sensors can switch device only once. See: https://www.juggluco.nl/Juggluco/sensors Wear OSThe phone version of Juggluco scans the sensor and sends this data to the WearOS version of Juggluco. Bluetooth on both phone and watch needs to be turned on. For fast transmission, also WIFI. After initialization, you can switch on and off directly connecting the sensor with the watch, with left menu→Watch→Wear OS config→Direct sensor-watch connection. https://github.com/j-kaltes/Juggluco/wiki#wearos-watches collects information about how well different watches work with Juggluco. Wear OS version contains complications to display the glucose level on a watch face. https://www.juggluco.nl/Jugglucohelp/introhelp.html

Juggluco requires just a little extra work and gives you MUCH more control over your alarms, visibility into how much insulin you have in your body at any given time, access to glucose and insulin levels on your watch and much more. On a recent trip, I lost access to my phone and was able to seamlessly switch control of my CGM over to my watch that was running Juggluco. I would have been lost without it. My only complaint is that I don't think there is a way to donate to the developer.

Juggluco keeps improving! Works well with Freestyle Libra 3+ sensors and is much better than the native app. Thank you
★★★★★Ben Holladay· Feb 27, 2026
A bit of a learning curve but what an improvement for tracking my Freestyle Libra 3+ sensor. Juggluco provides updates every minute (compared to 5 minutes from the Libra app) to my Pixel phone status bar, overlay, and to Watch Drip+ on my Amalfi Balance 2 watch. Still feeds data to LibreView, so I can generate reports for my doctor and my wife can get up-to-the-minute updates on LibreLinkUp.

Juggluco uphold my sanity! The Libra CGM sensors are the best, however the official app is lousy. Juggluco keeps me sane! With a bit of fiddling, you can even get your glucose reading on your Garmin watch. A real lifesaver! No NFC problems on my Samsung S25 under Android 16. NFC works with Abbot Libra 3 & 3+ and Nov open Ekko Plus.

Ok I just would like to see my libeling on my watch samsung 4, which I bought specifically. I walk a lot and to keep phone in hand is a pain. Positive feedback to help improve, thanks for your time/work, but it's very complicated in setup - too much unexplained and sorry poorly explained graphs/choices. So 6hrs on and I can't find the glucose watch face... hints please 🙏 in responce I don't understand your answer... I think you work on a higher level. The watch you're using and the face? Ta!

A great app if you can get it to work, but you may find yourself going round in circles through the settings and help getting confused and not succeeding. The in-app help is often difficult to follow and includes settings that appear to be redundant which doesn't help. For me the app will scan a value from the sensor, maybe after a couple of attempts, but does not maintain a connection for the streamed values. If you also want to link it with a watch that is another set of headaches.

As a software engineer of 30 years, I'd be embarrassed to attach my name to this jank. The user experience is one of the worst I've ever seen. You're greeted by a wall of unformatted, poorly written text. The interface is unprofessional to the point of mockery. The documentation is terrible. Error messaging is useless. I spent two hours trying to set up a Libre3 only to find buried in the documentation that it doesn't actually work with US Libre3. At least it's not vibe coded.
★☆☆☆☆Barry Moss· Nov 12, 2025
couldn't get it installed on my watch 7 then when I completely uninstalled this app my sensor keeps losing signal, so I have to keep res canning, don't want to uninstall Libra app as I will lose all my data
★☆☆☆☆Mike Coon· Jan 17, 2026
Can't get it to work. Can only view in landscape mode, it won't auto rotate. Won't connect to my G7 sensor.
