User reviews

A Very Underrated App, IMO

There are other Glucose apps, which charge for live activities not nearly as accurate and helpful as FLwatch. I started using this when I still had an Apple watch which I’ve since ditched because of the inexcusable battery life. Still use on my iPhone and the Live Activities update with my Librelink app immediately. Thank you for a great app with both privacy and great performance.

Works great

This app does what Libre 3 is too lazy to do, it talks to my Apple Watch! Yay! Now I have to figure out why it won’t talk to Apple Health.

Response from developer

Thanks for the review. Maybe some missing permissions for Apple Health? Please send an email to support if the problem persists.

This is exactly what the Abbot app is missing. Thank you very much for working on this!

Usefull

This app is great. It brings functionality that Freestyle should really supply via their app. Well done and thanks

Response from developer

Thanks. Glad it helps! 😊

At last, an app that’s practical!

love love love the app. User friendly and just sensible. Being able to easily see what’s going on at a glance without having to open apps and pressing a million buttons is amazing. My only suggestion/request would be to make the ‘resulting carbs’ button a free-fill option when we know the carb quantity already. Coffee donation on it’s way to you, it’s well deserved for making my (and my kids) life so much easier. Thank you!

Response from developer

Thank you so much for your review. I agree with the carb field. But I could not make it accepting input as well. And adding another field made everything too cluttered. My wprkaround: add the carbs on the carb/100g field, tap the 100g portion field and there you have the carbs you entered. 😊
