Why GlucoRelay Exists
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.

Help Me Test It
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:
- FreeStyle Libre 3 and Libre 2 users (every region)
- Dexcom Share users (G5, G6, G7, ONE)
- Nightscout self-hosted users
- Medtrum EasyView users (extremely rare — please come forward!)
- Parents using follower mode for their child
Take a screenshot anywhere in the app to send a debug report — no typing required. Or email support@approvethemove.com.
Important Disclaimer
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.
Privacy
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.
