Does Dexcom G7 work with Gyroscope?
Yes. Dexcom G7 can write its delayed glucose stream to Apple Health for Gyroscope to read.
The glucose series reaches the dashboard, but Apple Health receives it three hours late by Dexcom's design and carries no real-time alerts.
Short answer
Gyroscope has no direct Dexcom G7 integration. Dexcom G7 data reaches Gyroscope through Apple Health: turn on Dexcom G7's Apple Health sync, and Gyroscope reads what it writes. Dexcom documents a three-hour delay, so use the Dexcom app for current readings.
How the connection works
The sensor sends current readings to the Dexcom G7 app. After you activate Apple Health sharing in that app, Dexcom writes blood glucose records to HealthKit. Dexcom's official G7 instructions say Apple Health receives the information after a three-hour delay rather than in real time.
Gyroscope then reads the permitted HealthKit glucose series. Its glucose view activates at roughly 11 or more readings per day, the density expected from a continuous glucose monitor. The route is Dexcom G7 to Apple Health to Gyroscope, with no Dexcom account connection inside Gyroscope.
This handoff is useful for retrospective context, not live monitoring. The Apple Health permission is Blood Glucose, and Dexcom does not document its alerts, trend arrows, sensor state, or other app controls as Apple Health exports. Those remain in the Dexcom experience.
What syncs
Dexcom's Apple Health FAQ confirms the Blood Glucose write permission and its delay. The maker does not list other G7 app fields as Apple Health writes.
| Data | Writes to Apple Health | Notes |
|---|---|---|
| Glucose readings | Yes | Shared under the Blood Glucose category. |
| Real-time glucose | No | Apple Health receives readings after a three-hour delay. |
| High and low alerts | No | Dexcom does not document alert events as an Apple Health export. |
| Trend arrows | No | The Apple Health instructions only enable Blood Glucose records. |
| Sensor status | No | Use the Dexcom app for sensor and connection status. |
| Dexcom app settings | No | Alert and device settings stay in the Dexcom app. |
Set it up
- Set up Dexcom G7 with its compatible iPhone app and keep using that app for current readings and alerts.
- In the Dexcom G7 app, tap Connections, tap Apple Health, then tap Activate, following Dexcom's official steps.
- On the Health Access screen, turn on Blood Glucose and tap Allow.
- In Apple's Health app, open Sharing, select Apps, choose Dexcom G7, and confirm that Blood Glucose write access is on.
- Open Gyroscope, add Apple Health as a data source, and grant Gyroscope read access when iOS asks.
What you get in Gyroscope
Once the delayed glucose series reaches Apple Health at sufficient density, Gyroscope can place it on the same timeline as food, sleep, steps, workouts, and other sources. Glucose becomes one more tracked metric on the combined record instead of a number stranded in a separate app.
Food correlations can compare glucose with calories, carbohydrates, fiber, protein, and meal timing. The general correlations engine can also compare glucose with steps or other tracked variables, including lagged relationships and top-versus-bottom day differences.
The shared timeline does not turn Gyroscope into a live CGM receiver. The three-hour Apple Health delay remains part of every value on this route, while real-time alarms and treatment context stay with Dexcom.
Insights to try
- Glucose vs last food time.
- Glucose vs steps.
Treat the timestamp as a delayed HealthKit record and look at past patterns, not moment-to-moment decisions. Compare complete days with enough readings on both sides of the relationship, and keep current glucose checks inside the Dexcom app. Use identical day boundaries when you review the result.
Common questions
Why is my glucose three hours behind?
It is delayed by design. Dexcom's official FAQ says Apple Health receives G7 information after three hours, not in real time.
Can Gyroscope replace the Dexcom app?
No. Gyroscope is not a medical device. Keep using the Dexcom app for alerts and treatment decisions. Gyroscope uses the delayed Apple Health record for retrospective tracking.
Why do I not see a glucose view yet?
Gyroscope's automatic CGM detection needs roughly 11 or more readings per day. First confirm that Blood Glucose records are arriving in Apple Health, then allow time for a sufficiently dense day to sync.
Does this connect my Dexcom account to Gyroscope?
No. There is no direct Dexcom integration. Apple Health is the handoff between the Dexcom G7 app and Gyroscope.
