What Is Dexcom G7 Share and Follow?
Dexcom G7 Share is a built-in feature of the Dexcom G7 app that allows the sensor wearer to broadcast live glucose readings to trusted contacts called Followers. Followers install the free Dexcom Follow app and receive real-time data, trend arrows, and customizable alerts — without needing a separate receiver.
Requirements Before You Begin
- Dexcom G7 CGM sensor (active and calibrated)
- Dexcom G7 app installed on a compatible iOS or Android smartphone
- Dexcom Follow app installed on the follower's device
- Both devices connected to Wi-Fi or cellular data
- Active Dexcom account for the primary user
Step-by-Step Setup Guide
Step 1: Enable Share on the Primary Device
Open the Dexcom G7 app and tap the Menu icon. Select Share, then toggle Share ON. You will be prompted to confirm your Dexcom account credentials.
Step 2: Invite Followers
Within the Share menu, tap Invite Follower and enter the follower's email address. The follower receives an email invitation with a download link for the Dexcom Follow app.
Step 3: Follower Account Setup
The follower taps the email link, downloads the Dexcom Follow app, and signs in or creates a free Dexcom account. Once accepted, live glucose data appears on their screen within minutes.
Step 4: Customize Follower Alerts
Followers can independently set their own alert thresholds for high glucose, low glucose, signal loss, and urgent low — providing flexible oversight without disrupting the primary user's settings.
Share vs Follow: Feature Comparison
| Feature | Primary User (Share) | Follower (Follow App) |
|---|---|---|
| Live glucose readings | Yes | Yes |
| Trend arrows | Yes | Yes |
| Custom alerts | Full control | Independent control |
| Calibration | Yes | No |
| Max followers | Up to 10 | N/A |
Troubleshooting Common Issues
- Follower not receiving data: Ensure both devices have active internet. Re-toggle Share off and on.
- Invitation email not received: Check spam folder; resend from the Share menu.
- Data delay over 5 minutes: Check phone Bluetooth is enabled and the sensor is within range (6 metres).
- App crashes: Update both apps to the latest version from the App Store or Google Play.
Tips for Caregivers and Parents
The Follow app is especially valuable for parents of children with Type 1 diabetes, enabling overnight monitoring without disturbing the child. Set the Urgent Low alert (under 3.1 mmol/L) as a mandatory alarm to ensure rapid response.
For reliable, uninterrupted CGM monitoring, ensure your child is using a genuine Dexcom G7 sensor from a trusted supplier. Explore the full range of Dexcom G7 sensors at MDS Diabetes — the UK's leading diabetes supplies specialist.
