Glucose Relay

LibreLink shows your glucose but, in many countries, does not save it to Apple Health. Glucose Relay does that one job: it copies your FreeStyle Libre readings into Health, automatically. WHY PUT GLUCOSE IN HEALTH Your glucose sits beside your sleep, activity, and heart rate, stays in your own long-term record, and can be shared with your care team or with apps you choose. HOW IT WORKS Glucose Relay follows your sensor through LibreLinkUp, Abbott's sharing service, the way a family member would. You sign in with a LibreLinkUp account that follows your own sensor, turn on Health, and that is all. It updates about once an hour on its own and every minute while it is on screen. Each update covers the last twelve hours, so a missed hour is filled in by the next one. THE LAST 24 HOURS A list of every reading Glucose Relay saved to Health in the past day, newest first, in your own unit, so you can see what was saved without leaving the app. WIDGETS Your latest reading, with its trend arrow and how old it is, on the Lock Screen and the Home Screen. The widgets fetch on their own about every fifteen minutes, or less often if you choose, so they stay current even when the app has not run for a while, and they mark a reading that is older than fifteen minutes. The Home Screen sizes add a chart of the last twelve hours. APPLE WATCH Your latest reading on your wrist, in the Glucose Relay watch app and as a complication in the corner, circular, rectangular or inline slot of your watch face. Open the watch app once with your iPhone nearby, and it takes your sign-in from there; after that it fetches on its own, at the interval you chose for the widgets, and marks a reading older than fifteen minutes. Needs watchOS 10 or later. PRIVATE BY DESIGN Readings go from Abbott to the Health app on your iPhone and nowhere else. There is no Glucose Relay account, no server of ours, no analytics and no tracking. Your password is kept in your iPhone's Keychain and sent only to Abbott; if you use the watch app, the iPhone hands it to the watch's Keychain once, over Apple's encrypted connection between the two. WHAT YOU NEED A FreeStyle Libre sensor with the LibreLink app, and a free LibreLinkUp account connected to it. The app walks you through setting that up. GOOD TO KNOW Your iPhone has to be unlocked for readings to be saved, because Health is sealed while the phone is locked. Leave Glucose Relay in the app switcher rather than swiping it away, and it keeps working in the background. Low Power Mode pauses background updates. IMPORTANT Glucose Relay is not a medical device and not an alarm. It does not replace LibreLink. The widgets show readings for information only. Do not use it for treatment decisions. Glucose Relay is an independent project. It is not affiliated with or endorsed by Abbott. FreeStyle Libre, LibreLink and LibreLinkUp are trademarks of Abbott.
