Patient Considerations


Many components. Have to carry pens, smart caps, pen needles, and CGM is attached to the body. 

Active Lifestyle

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

Limited customizability. System integrates the FreeStyle Libre 2 CGM for high/low alerts but requires manual dose adjustment and limits the ability to adjust basal insulin throughout the day. 

Easy to Use

Simple design. One-button device with easy to read display.

Easy Insulin Dosing

Dosing recommendations. Displays dosing recommendations and reminders for long-acting insulin. 

Fewer Fingersticks

Factory-calibrated sensor. Finger sticks needed for backup only. 


Hideable. Pens are portable but visible when in use. Frequent injections are unavoidable. Sensor is the smallest option available.
