FLwatch displays blood glucose readings from Abbott FreeStyle Libre 2 and Libre 3 sensors on your iPhone and Apple Watch using the LibreLinkUp cloud. It also lets you record insulin doses and visualizes insulin-on-board and insulin activity with dedicated graphs, helping you better understand how insulin and glucose levels interact.
With native Apple Watch support, widgets, and Live Activities, your glucose data is always visible across your Apple devices, helping support daily diabetes management.
FLwatch is free and open source.

Downloaded this app so I can see my levels on my watch. It works with the Libre Style 2 sensor just had to put my Libre log in details into this app and it connect to my Libre sensor straight away. I then added this app to my watch face so I can see it all the time without having to open the Libre app!
Fab and easy to use

This is the app that Freestyle Libre sensor users need (ie all the missing functionality that Abbott can’t be bothered supply as standard!).1. Integration with Apple Watch using the LibreLinkUp data. Very easy to set up, especially if you’ve already done this yourself share data with your GP/DSN. FYI I use the modular watch face and set the complications to update every 20 minutes. 2. Ability to record IOB - no idea why LibreLink doesn’t do this - prettier y essential. The app is free, but I’ve bought the developers some coffee and recommend you do the same 😀
Incredible app

Great and simple app. Makes up for the lack of watch support natively from the Freestyle Libre
Developer Response
Thanks! Glad, it is useful. 😊
* full CarPlay support
* Note: FLwatch currently supports the LibreLinkUp 4.x.x API. Abbott has released API 5.0.0, which is not yet supported. If Abbott disables API 4.x in the future, glucose data in FLwatch may stop working without notice. IOB-related features will still continue to work.
