Great program. Please can I suggest 2 small improvements

Great programme, works very well, a huge improvement over the Freestyle libre app.
There are only two small things that I would love to see in any future update.

Support of NTF to download smart insulin (novopen 6) data.

Also a quiet pre alarm, alarm.
Maybe 30 seconds before the main alarm goes off for low, hi etc, could we have a quiet vibrate alert. Then 30 seconds later the current main noisy wake you up alarm.

At night I’m often awake and would hopefully hear a quiet vibrate alert, 30 seconds before main alarm activates?
It would give enough time to quickly check the reason for the alarm and silence the main alarm before the main alarm activates and wakes my wife up, who sleeps next to me.

Thank you for all your great work.
5 star.

Big thank you for publishing this app!

Thank you for having this available for the world 🙏🙏

Great but..

Iv been using zukka since March 2026. I use a stelo dexcom. It’s been great but recently it’s been all the sudden stopping my readings. Idk why. It’s still Bluetooth connected to my phone and dexcom and I need these readings. I go into 30’s in my sleep and I’m scared to sleep and not knowing if I’m low or not. Please respond quickly!!

Flaky

Move to this after the demise of Shuggah. I use Freestyle libre EU and the signal keep disconnecting. So you might think your BG is ok but it may have rises or dropped lower than you’d like.

10/10

Після 2 днів роботи LibreLink вибив вікно що сенсору капут, і більше не підключався до нього. Ні на що не надіючись, спробував Zukka, і виявилось що з сенсором все окей 😍
