†If your glucose alerts and readings from the Dexcom G6 do not match symptoms or expectations, use a blood glucose meter to make diabetes treatment decisions.

Only use this app if you have the Dexcom G6 CGM System.

Dexcom G6 provides real-time glucose readings as frequently as every five minutes. Dexcom G6 is approved for children age 2 and older.

The Dexcom G6 System provides personalized trend alerts right on your smart device and lets you see when your glucose levels are going too low, or too high, so you can better manage your diabetes. The Alert Schedule feature lets you schedule and customize a second set of alerts. For example, you can set the schedule to match your work hours and have different alert settings during the rest of the day. Custom alert sounds are available, including a Vibrate-Only option on the phone for glucose alerts other than the Urgent Low Alarm.

The Always Sound setting allows you to receive certain Dexcom CGM Alerts even if your phone sound is off, set to vibrate, or in Do Not Disturb mode. This will allow you to silence calls or texts but still receive audible CGM Urgent Low Alarm and alerts: Low and High Glucose alert, Urgent Low Soon, and Rise and Fall Rate. Please note that when your phone is set to Silent or Do Not Disturb, you will not receive any audible alerts for Signal Loss. Always Sound is on by default. A Home screen icon shows you if your Alerts will sound or not. For safety, the Urgent Low alarm and three alerts (Transmitter Failed, app Failed, and Sensor Failed) can’t be silenced.

In addition to the accurate performance provided by the Dexcom Sensor, you’ll receive other valuable features:
• Share your glucose data with your followers who can monitor your glucose data and trends on their compatible smart device with the Dexcom Follow app.ǂ
• Health app access so you can share retrospective glucose data with third party apps
• Today View widget, which allows you to view your glucose data on the lock screen of your smart device

ǂDo not make treatment decisions based upon Share and Follow information. Always confirm on your Dexcom G6 compatible smart device or receiver. Internet connectivity is required to access the Dexcom Follow app.

No widgets

The website says you can add a widget to your Home Screen of the G6 but this app still doesn’t allow this functionality?

If it stayed working how it supposed to it would be amazing

App crashes constantly. Stops receiving data. Stops sharing data. When it does work, it’s great. But for the amount of money that we spend on the Dexcom G6 the app should work better.
