My son wears a Medtronic 780G pump. His cousin uses Dexcom G7. My friend's daughter just switched to a FreeStyle Libre. Every family I know juggles two or three different CGM apps that don't talk to each other.
I wanted one app where I could see all of them. Sugarmate is Dexcom-only. Happy Bob is Dexcom-only. Every vendor app supports its own brand. So I built GlucoRelay.

MiniMed 670G, 770G, 780G, Guardian — 40+ countries.
Self-hosted open-source CGM cloud.
Nano and TouchCare A7+ support.
Any CGM that syncs readings to Health.

“Hey Siri, what's my blood sugar?” Works with any source.
I own a Medtronic CGM. To verify GlucoRelay works correctly with every other CGM brand, I need testers from across the diabetes community. The TestFlight beta is open with no waitlist.
Especially looking for:
Take a screenshot anywhere in the app to send a debug report — no typing required. Or email support@approvethemove.com.
GlucoRelay is not a medical device. It is a viewer that reads data from the CGM cloud service you already use. Always verify readings with your primary CGM receiver before making treatment decisions. GlucoRelay is not affiliated with Dexcom, Abbott, Medtronic, Medtrum, or any CGM manufacturer.
GlucoRelay runs with zero backend. Your CGM credentials stay on your device in the iOS Keychain. HealthKit access is read-only. No analytics, no tracking, no advertising. Follower sharing uses Apple CloudKit; readings expire after 24h.
