### 3/5 — Follow app syncing?

*2026-08-26*

Can this be used with Dexcom follow app as I am a T1D parent and would like to have access to these widgets?

### 5/5 — Follow app - Dexcom

*2026-08-22*

Highly recommend. We use this for following with Dexcom.

### 5/5 — Absolutely amazing!

*2026-07-25*

Love the app! Its live activity restarts on its own and it does the work that not even the original dexcom app does on my iPhone. You can see the real time numbers on the dynamic island and also your lock screen and the best part it also displays the minutes when it was last refreshed. Definitely recommended especially for iPhone users.

### 5/5 — Great app!

*2026-06-04*

Great app but how do you change the readings on watch to mmol/L. I have been able to do it on my phone but not on the watch. Thank you

### 5/5 — Way better than Dexcom

*2026-05-04*

The UI issues with the G7 widgets and the consistent way the G7 doesn’t update reliably on Apple Watch drove me crazy for years. Luka is a complete game changer, works so much more reliably. The UI is elegant and practical.

### 4/5 — Great on iPhone but watch app not functional

*2026-04-17*

Great alternative to Dexcom interface. But I’d hoped it would offer a more reliable and useful way to monitor glucose via Apple Watch. While it’s possible to install Luka, the app itself doesn’t open and just crashes instantly. Any updates/advice on this would be excellent. Thanks for all your work!

### 5/5 — Unbelievable

*2026-02-23*

Clearly made by someone who truly cares unlike Dexcom’s so called “widget”. Thank you.

### 5/5 — Millions thank you for that app

*2026-02-19*

So important to see level of sugar for kid. Thank you for make this application

### 3/5 — Love the app but the latest update messed up reliability.

*2026-02-11*

This app is simply amazing. I appreciate the dev’s willingness to improve it but the latest update causes it to fail frequently. Go back to the previous version!

### 5/5 — Much better than the Dexcom app

*2026-01-21*

I really like the Mac app too

**Developer response:** Hi there! Widgets are given a limited "refresh" budget, and Luka tries to refresh as often as possible. When you first add a widget, the system gives it a smaller budget, but if it's viewed often, it's given more refreshes, so over time you should see this improve. You can also set up the widgets to refresh when you tap them. Let me know if you're still seeing issues. Thanks!
