What's New in Luka

2.8.1

July 1, 2026

→ Luka now supports automatically restarting Live Activities, allowing them to run forever instead of ending after ~8 hours. → Readings outside of the supported range (40-400) now correctly show "low" or "high" instead of showing an inaccurate reading. → Fixes an issue where Luka would appear to log you out if you launched the app quickly after rebooting. → Improved Live Activity layout on Apple Watch.

Way better than Dexcom

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.

Unbelievable

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

Millions thank you for that app

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

Love the app but the latest update messed up reliability.

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!

Much better than the Dexcom app

I really like the Mac app too

Response from developer

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!
