Juggluco 2.3.18 [free]

Abbott's Freestyle Libre 2 sensors transmit every minute the perceived glucose value to the connected reader or smartphone. Abbott's Librelink app uses this
value only for low and high glucose alarms. Juggluco displays this value on the smartphone in addition to low and high glucose alarms. So you can know your current glucose
value without scanning; making devices on top of the sensor (like Blucon) unnecessary.
You can install Juggluco beside Abbott's Librelink app, so you can see yourself how Juggluco performs in comparison to Librelink. The values received via Bluetooth are
identical or differ minimally from the current glucose value received by scanning, but the values can fluctuate so that a moment later a different value is shown. The
history values (the values of the last 8 hour received by scanning from the sensor, shown in the Daily Graph of the Librelink app) are different; they are less extreme than
the scanned and streamed (Bluetooth) values.
The glucose values are influenced by previous readings; thus although Juggluco and Abbotts Libre app determine glucose values the same way, they can differ when one of them
is used longer. While using Juggluco and Abbotts Libre app beside each, differences will decrease with time.
Juggluco can only take over the Bluetooth connection of a sensor that is already in use, when ALL COMPETING CONNECTIONS WITH THE SENSOR ARE REMOVED by FORCE CLOSING the
Libre app and turning off Freestyle reader or turning off alarms of these apps and devices. Hereafter you scan the sensor a few times with your smartphone while Juggluco is
in the foreground and, when everything goes well, within 20 minutes or less Juggluco will establish a connection with the sensor and start receiving glucose values via
Bluetooth. Juggluco gets during NFC scanning a new Bluetooth authentication for the sensor and Librelink's Bluetooth authentication will not work anymore.
In addition to the Bluetooth stream of glucose values, Juggluco displays the result of scanning: the current value and past 8 hours history out of the memory of the sensor.
All in one detailed graph.
You can also add your amounts of insulin, carbohydrate and activity to the graph.
If enough data is gathered (9 days) summary statistics are generated from the Bluetooth stream data: time in range, estimated A1c and a summary graph.
Juggluco can send glucose values to smartwatches in three ways:
- by creating an Android notification redirected to smartwatches (Notify);
- via watch app Kerfstok running on some Garmin watches;
- via xDrip watch apps on all kinds of smartwatches;
- Juggluco for Wear OS.
Starting with Juggluco 2.2.1, Juggluco can also be used with US Freestyle Libre 2 sensors.

Wear OS
There exist now a Wear OS version of Juggluco adapted to the small screen. It also contains a watch face that displays the glucose value received from
the sensor every minute. Every sensor has to be initialized by an Android phone running Juggluco, which sends data to the Wearos version of Juggluco via TCP. In my
experience the Wearos version of Juggluco performs best when staying connected this way, receiving the glucose values from the phone version of Juggluco every minute.
It is also possible to switch the connection of the sensor to the Wear Os watch. For this to work as good as when the sensor is connected to the smartphone, you probably
need a smartwatch with very good Bluetooth connectivity or find out what is interfering with the Bluetooth connection during physical activity. If the sensor is connected to
the watch, the data can also be sent from the watch to the phone.
More information is in the phone version of Juggluco under Left Menu->Watch->Wearos Config->Help.
