Juggluco - what is it and why are more and more people with diabetes using it?

Juggluco is an unofficial but highly advanced app for real-time glucose monitoring. For many CGM sensor users, it’s an alternative that offers more control, more data, and more capabilities than standard manufacturer apps.

What is Juggluco?

Juggluco is an Android application created by an independent developer that allows reading data from continuous glucose monitoring (CGM) sensors – without the need to use official manufacturer apps.

The app connects directly to sensors via Bluetooth and displays glucose levels in real time. It supports among others.:

FreeStyle Libre 2 / 3
Dexcom G7 / ONE+
Sibionics
Accu-Chek SmartGuide

This way, you can have full control over your data – without the limitations imposed by manufacturers.

What makes Juggluco stand out?

🔴 Real-time data

Juggluco receives readings even every minute and displays them without delays – without the need to scan the sensor.

📊 Advanced charts and statistics

The app shows a detailed glucose curve and standard statistics that help better understand trends.

⌚ Smartwatch integration

You can send glucose data directly to your watch (Wear OS), and even display it on the watch face.

🔊 Notifications and voice readout

Hypo/hyper alerts and the ability to read results aloud – useful, for example, at night.

🔗 Integrations (Nightscout and more)

Juggluco can send data to:

Nightscout - can be used with https://diab.ninja/en#features
LibreView
Health Connect

and share it with other apps or devices.

Who is Juggluco for?

This tool will be especially appreciated by:

people using Nightscout
parents of children with diabetes
users who want more than the official app provides
people who like full control over their data

Juggluco is often chosen by more advanced users – especially those who build their own ecosystem (e.g., watch + Nightscout + automations).

Is Juggluco official?

No – it is an independent application.

This means:

no official support from sensor manufacturers
greater flexibility, but also greater responsibility on the user’s side

Despite this, the app is actively developed and used by the diabetes community worldwide.
