About this app

Only use this app if you have the Dexcom G6 or G6 Pro CGM Systems.

Always know your glucose number and where it’s heading with the Dexcom G6 and G6 Pro Continuous Glucose Monitoring (CGM) Systems –indicated for diabetes treatment decisions with zero fingersticks and no calibration.*

*Fingersticks required for diabetes management decisions if symptoms do not match readings.

Always know your glucose number with just a quick glance at your compatible smartphone or smartwatch. For a list of compatible devices visit Dexcom G6 and G6 Pro provide real-time glucose readings for patients with type 1 or type 2 diabetes every five minutes. Dexcom G6 and G6 Pro are indicated for children age 2 years and older.

The Dexcom G6 and G6 Pro Systems provide 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. The only exception is the Urgent Low Alarm, which you can’t turn off.

The Always Sound** setting, which is on by default, 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 Alarm and Alerts, including the Urgent Low Alarm, Low and High Glucose alerts, Urgent Low Soon Alert**, and Rise and Fall Rate alerts**. A Home screen icon shows you if your Alerts will sound or not. For safety, the Urgent Low Alarm and three alerts cannot be silenced: Transmitter Failed, Sensor Failed, and App Stopped.

Other features:
• Share** your glucose data with up to ten followers in real time. Followers can monitor your glucose data and trends in real time on their compatible smart device with the Dexcom Follow** app. Share and Follow functions require an internet connection.
• Samsung Health and Google Health access so you can share retrospective glucose data with third party apps
• Quick Glance allows you to view your glucose data on the lock screen of your smart device

**Not available on Dexcom G6 Pro System

It works. It does not excel at anything. Events, 2 stars. People have been asking for notes every since the beginning. It still isn't there. Settings policies are too tight. They don't take into account user needs. (alert timing, alert volumes, etc) I should also be able to create events from the horizontal graph screen.

It's been 7 months since the app conncted with the transmitter. Non of the recommendations from the customer service worked. Edit: It turns out the reason why it was not connecting is because of changes in android. After upgrading to android 12 it is working and the reading are transmitted with no problem. Unfortunately it is not accurate anymore. I don't know what kind of changes you made on the algorithm it is consistently wrong compared to the blood test.

It's great to use phone rather than separate receiver. It would be nice if the 90-day warnings about transmitter battery expiring were a different color or at least very visually different from the regular 10-day warning that a sensor is expiring. I got caught with no replacement transmitter after failing to distinguish that from the regular 10-day warning.
