User reviews

not working as well as it used too

Ever since the most recent update, I’ve noticed that the app is not staying connected to my Stelo. I’m not sure if it’s a change in the app or in the most recent iOS update. To be clear I am still on 26 but the most recent version of 26. Fingers crossed it’ll work itself out.

Used to be good

I used to like this app but the last week has been horrible. The app is not connecting to my Stelo. I finally deleted the the app loosing my history and redownloading it. It finally connect but is not giving the same numbers as the Stelo. It has become so unreliable. Add to the fact that contacted the developer to let them know the dark blue icons ona black background make it hard for people to see the icons. His only answer was go to the forums and ask. Like the forums will do anything. Over all not worth using at this time

Great option for Apple Health

I’ve tried a number of setups and came across the Zukka app. It works great (iPhone 16 Pro, iOS 26, Libre 3+, Libre app, LibreLinkUp, Apple Health).

Abbott doesn’t provide a data feed to Apple Health. I tried a couple of different combination solutions, but this is straight forward and doesn’t require any third party stuff. Watch app is nice too, and the activity can even show on my CarPlay.

Zukka app in follower mode, with heartbeat tied to sensor via Bluetooth. So I get a pretty full set of data, limited only to when the Libre app isn’t collecting data from the sensor.

I’m Type 2 so I’m not linking to a pump or other device. Just my iPhone.

Definitely use the xDrip4iOS Facebook page for support. Read it. It will answer most questions, and the support is great.

And a big thanks to the developer who keeps it updated in the App Store.

EDIT: App works well now after 12ish week wait

Latest app update allowed stelo to be paired almost instantly now. Not sure why it was an issue before, but i’m glad it’s working now!

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.
