Summary
Good to have. Tried and true. Backup or day to day. Fingersticks required.
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
Components
Generic Meter : Lancets
Tiny needle called a lancet is used to poke the skin (on a finger or on your arm) to get a small sample of blood. The lancing device is packaged with the glucometer.
Generic Meter : Test Strips
The strips work with the glucose meters to “read” blood sugar levels. One box of test trips usually contains between 25-50 single use strips.
Meter : Glucometer
The meter measures the amount of sugar in the small sample of blood that is placed on the disposable test strip. Most CGMs require testing blood sugar with a meter to calibrate the CGM device daily.
Tandem Mobi : Pump
Small pump connects tubing to a 5 inch tubing patch called an infusion set that attaches to the body.
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.

Patient Considerations
Active Lifestyle
Must pause activity to check blood sugar.
Waterproof. The pump and CGM are waterproof and can be worn for most exercises.
Avoiding Highs and Lows
Less data. Meters don't give as much blood sugar data as sensors do and require a high level of engagement and effort to avoid 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.
Comfort
Meter supplies carried and requires visible blood.
Shorter tubing option. A shorter 5-inch tubing option for comfort on body.
Easy Insulin Dosing
Limited features. No info on blood sugar trends.
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.
Easy to Use
Large display. Device typically has large display numbers for easier readouts, and it's very simple to operate.
Easy Dosing. Full control from a smartphone, with the option to manually bolus if needed.
Fewer Fingersticks
Frequent fingersticks are unavoidable.
Factory-calibrated sensor. Fingersticks needed for backup only.
Privacy
No attached device for blood glucose monitoring.
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.
