A complete glucose picture

The Dexcom G7 app gives you a continuous look at your glucose levels on one simple screen. With just a quick glance, you can see where you’re at, where you’re heading, and where you’ve  been, without needing to scan or take a fingerstick§. With real-time data, you’re able to see how food and activity affect your glucose levels in the moment, making it easier to make more confident decisions.
The mag glass at the top of the screen is your current glucose value. Around the mag glass is an arrow that shows you which direction your glucose is trending: up, down, or steady. And below the mag glass is your trend graph providing an easy way to visualize what your glucose levels have been doing over the last 3, 6, 12, and 24 hours, so you can start to identify trends.
§Fingersticks required for diabetes treatment decisions if symptoms or expectations do not match readings.

Clarity insights in the app

New to the Dexcom G7 app is the integration of Dexcom Clarity. Underneath the trend graph on the glucose tab you will see a Clarity summary. This paints a picture of your progress and helps you visualize high or low trends over the last 3, 14, 30, and 90 days.

Customizable alerts help keep your glucose in range.

Dexcom G7 has a fully customizable set of alerts that allows for an abundance of flexibility to manage diabetes your way. Alerts are designed to warn you of high or low glucose levels and can help you spend more time in range.2-6
  • The Urgent Low Soon alert provides a 20-minute advanced warning of potentially dangerous low glucose levels so users can act proactively and stay in range. So far, Dexcom patients have acknowledged more than 52 million Urgent Low Soon alerts—more than 11 million of those in the middle of the night10
  • With Dexcom G7 you can also customize a Delay 1st Alert setting for your High Alert. Turn it on to delay your first alert until your sensor reading is at or past the alert setting for the time you specify. For example, if you set Delay 1st Alert to 20 minutes for your High Alert, your glucose must be at or above your high alert level for 20 minutes before you get the alert. This is especially helpful if you know you’ll be higher while you are waiting for your insulin to start working.
  • The Silence All setting can be enabled for up to 6 hours, giving you total silence when it’s needed. When this setting is enabled, all Dexcom G7 alerts will be silent, and you will not hear sounds or feel vibrations related to any alerts.

Log features for enhanced insights

Another new feature of the Dexcom G7 app is the ability to log and track events. As you go throughout your day, you can quickly navigate to the “History Tab” and tap the “+” button. A menu will pop up and you can log:
  • Blood Glucose – Fingerstick or calibration
  • Insulin – Fast- or long-acting dose
  • Meal– Carbs you’ve eaten
  • Activity – Duration and intensity
  • Notes – Add any additional information you would like to record in your app
