User reviews

Follow app syncing?

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

Follow app - Dexcom

Highly recommend. We use this for following with Dexcom.

Absolutely amazing!

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.

Great app!

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

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.
