The app takes BGL from Libre site, or for one other sensory type. It took a little tweaking to get working. With Libre Freestyle it’s important to realise that it doesn’t take the readings directly from LibreLink, but from LibreLinkUp. Get both apps and register your Libre Freestyle sensor on LibreLinkUp. After that your BGL will be drawn from that site rather than directly from the sensor. That gives limits, such as no updates while in airplane mode or no internet connection. But other than that I can my blood glucose readings on my watch and I can put a chart on my phone lock screen, meaning I can stay always up to date. In addition it will send and receive to Health, a feature I desperately wanted for the Libre freestyle.
Developer Response
Thank you for the thoughtful review and for explaining the LibreLinkUp setup so clearly, that is exactly how the Libre connection works and your write-up will help other users. A lot has happened since version 1.2: Sugar Sense 2.0 is now live with a full redesign, Dexcom and Nightscout support, Apple Health as a glucose source, an AI food scanner, daily insights and a Morning Report, detailed statistics with Time in Range and AGP, and Care Circle so family members can follow your glucose and get alerts. Update to 2.0 and let us know what you think at support@sugarsense.io. Thanks for being with us!
Great resource

Developer Response
Thank you, Julian! Clean and simple is exactly what we go for: everything you need to stay informed at a glance, and nothing you do not. If an idea for making it even better ever comes to mind, we are always listening at support@sugarsense.io. Thanks for taking the time to write this!
