Patient Considerations
Active Lifestyle
Water-resistant for up to 3 feet deep for 30 minutes and light on the body, does not get in the way of activity.
Light on body. Pens are easy to use and do not remain attached to the body, senor is light on the body.
Avoiding Highs and Lows
Optional glucose alerts for low and high glucose levels. Trend arrows show the direction glucose is heading, with the rate of change.
Limited customizability. System integrates the Dexcom G6/G7 CGM for high or low alerts but requires manual dose adjustment and limits the ability to adjust insulin levels throughout the day.
Comfort
Lowest profile sensor and smallest adhesive (about the size of two stacked U.S pennies).
Many components. Have to carry pens and pen needles. CGM is attached to the body.
Easy Insulin Dosing
Sensor trends can be used for dose adjustment.
Dosing recommendations. Displays personalized mealtime dosing recommendations.
Easy to Use
No scanning required. Minute-by-minute readings are sent directly to the mobile app.
Simple design. Replaces regular insulin pen. No additional devices to add on.
Fewer Fingersticks

Privacy
