Customizable alerts that work for you.

The Dexcom G7 app gives you the flexibility to customize alert sounds and settings to best fit your lifestyle and needs.
Urgent Low Soon
Provides a 20-minute advance warning of when you’ll reach 3.1 mmol/L so that you can act quickly and avoid a potential hypoglycemic event.
Silence All
With this setting, all alerts will not sound or vibrate for up to 6 hours. Visual notifications will still appear on the lock screen.
Delay 1st Alert
Enables you to delay your first High alert until your sensor reading is high for a while, allowing you to make your glucose alerts work for you.
Quiet Mode
When this setting is enabled all your Dexcom G7 alerts will vibrate. Your Urgent Low Glucose and Technical Alerts will still escalate to sound if not acknowledged.
Urgent Low Alert
Alerts you when your sensor reading is at 3.1 mmol/L or below. This alert cannot be turned off or silenced.
Low Glucose Alert
Alerts you when your sensor reading is at or below the level you set. Customize this setting to enable tighter control and help get ahead of lows.
High Glucose Alert
Alerts you when your sensor reading is at or above the level you’ve set. It’s the yellow line on the trend graph.
Rising & Falling Fast Alerts
Let's you know when your sensor readings are changing quickly. You’ll see double arrows on your glucose reading. These alerts can be turned off in the Profile tab.
Clarity with the G7 app

Track your progress. Reach your goals.

You can track your progress by viewing the integrated Dexcom Clarity card right in the Dexcom G7 app. View insights into your glucose patterns simply by swiping up to view the Clarity card. The more you know, the easier it is to stay in range, which can help lower your A1C.3-8
