I'm happy to report that Dexcom has added watchOS support to their own first party iOS application. This is a great step forward in helping us diabetics keep an eye on our glucose levels.
There also seems to be some exciting rumors floating around that the next version of the Apple Watch will have blood sugar monitoring built in. The watch data would be gathered through a sensor requiring only skin contact. The data would likely not be as accurate as the subcutaneous sensors Dexcom currently uses. However, combined with the subcutaneous data the wrist data could be used to make our entire monitoring system much more accurate. Though nothing has been announced yet, I think it is an encouraging sign that Apple announced a partnership with Dexcom at this year's WWDC.
Anyway, back to watchSugar. While it was a fun project and extremely helpful for us diabetics who used it to monitor our blood glucose levels directly on our watches, watchSugar was always a hack. It worked periodically making web requests to Dexcom's website. This is a lot of extra data and battery usage just to retrieve information that originated from a personal device that was also attached to you. Now that Dexcom has added first party support, there is no reason for watchSugar to be around.
watchSugar remains open sourced on github. Thanks to everyone who helped me develop and test the app initially. May your glucose levels always remain low, but not too low. (👊 Diabetic fist bump).
