Summary
The Tandem Mobi is the smallest durable automated insulin delivery system available in the U.S. that can be fully controlled by a mobile device. The pump is equipped with an on-pump button for users to bolus insulin directly from the pump if they don’t want to do it from their phone. This system is combined with the Dexcom continuous glucose monitor (CGM) to automatically adjust insulin delivery in response to glucose trends.
*Compatiblilty with Dexcom G7 now available
The Medtronic Guardian Connect is a continuous glucose monitoring (CGM) system that provides real-time glucose data on a compatible smartphone. The system offers optional low and high blood sugar notifications and can be inserted on the abdomen or back of the upper arm.

Tandem Mobi : Sensor
Automatic applicator inserts sensor just under the surface of the skin and can be applied to many places on the body.
Tandem Mobi : Controller
Mobi pump receives CGM readings to automatically adjust basal insulin delivery via an infusion set. Compatible smartphone can be used to view and control insulin delivery.
Tandem Mobi : Infusion Set
An infusion set contains the thin plastic tubing that delivers insulin from the pump to the body.
Guardian Connect : Sensor
Sensor is inserted underneath the skin, either on the abdomen or arm. Push buttons applicator allows sensor to be placed on the body in one step.
Guardian Connect : Transmitter

Patient Considerations
Active Lifestyle
Waterproof. The pump and CGM are waterproof and can be worn for most exercises.
Waterproof transmitter when submerged in up to 2.5 meters of water for 30 minutes and must be within 20 feet of a connected mobile device.
Avoiding Highs and Lows
Auto basal and bolus insulin. Responds to CGM data by increasing or decreasing basal insulin delivery to prevent highs and lows and maintain a set blood glucose target.
Measures sensor glucose 24/7 and sends alerts when a high or low is detected. Trend arrows show the direction glucose is heading, with the rate of change.
Comfort
Shorter tubing option. A shorter 5-inch tubing option for comfort on body.
More tape is needed for Medtronic sensors.
Easy Insulin Dosing
Automatically adjusts dosing. Sensor integration allows the pump to automatically adjust insulin doses. More customizable dosing than pens or syringes. Manual bolus button is available for quick dosing without a phone.
Sensor trends can be used for dose adjustment.
Easy to Use
Easy Dosing. Full control from a smartphone, with the option to manually bolus if needed.
Rechargeable sensor transmitter but has the most steps to change sensor.
Fewer Fingersticks
Factory-calibrated sensor. Fingersticks needed for backup only.
2 daily finger-sticks are needed to calibrate the sensor.
Privacy
Discreet. Ability to check blood sugar on phone or watch. Ability to bolus on a compatible smartphone. Pump has tubing but can be clipped to clothing or attached to local area with an armband or adhesive sleeve to be discreet when needed. Dexcom's built-in hypoglycemia safety alarm alerts users when glucose is below 55 mg/dl and is always on.
Somewhat discreet. Ability to see sugar on watch or phone. Sensor requires regular meter use.
