I am prescribed Dexcom One on the NHS for about 18months. At first I was surprised to find the Dexcom One app has nowhere to record food, insulin and exercise, but on this forum I learned that the Sugarmate app links with Dexcom and have used this app to store all my information since. Yesterday Sugarmate stopped receiving glucose readings from the Dexcom One app. Sugarmate say it's because "Dexcom One doesn't work properly with Dexcom's real-time Partner Web API" and there's nothing they can do. I have reached out to Dexcom but wondered if any other Dexcom One users have had a problem with Sugarmate or if there are any other apps which link with Dexcom One. Thanks and Seasons Greetings to all.
