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.* A core feature of the Dexcom G6 and G6 Pro Systems is providing users with alarm/alerts based on their glucose level.

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

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.

Health Connect 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

Wear OS Integration allows you to view glucose alerts and alarms from your Wear OS watch.

I can only view historical readings within the hour. It keeps a record of it, a log, by hovering over the little dot that represents a five-minute increment. But anything more than that, the three hours or six hours or 12 hours or 24 hours, I can't see anything. I'll drink the line across each of the 5 minute increments in any of those other windows, 3, 6, 12, 24 hours, It doesn't show me any numbers. I've cleared the data, the cache and data for the app. I've logged out and back in, reinstall

I've been using the G6 for almost 2 years now and it started off great, but lately it's inaccurate and I have to constantly calibrate it using the old finger stick method. Now the app doesn't even show your readings throughout the day no matter what time frame you choose (1, 3, 6, 12 or 24hr) which is really dumb. It only shows what's reading at that time. Customer support said to download the Clarity App, but that has nothing to do with the glucose history on the G6 app. Switching to Libre.

I had to delete my old review because there is no where else to be able to type out my issue. On Google Pixel phones, there's been an update that is not allowing some notifications to push there. my phone used to make sound when I was getting a high or low blood sugar, even when my phone was on vibrate or silent, but it no longer allows for that. Sometimes it will still sound for a low, but only really short. I already wrote an issue to Google about this, but would love more support.
