Summary
Connected smart caps that recommend insulin doses for people using multiple daily injections. This system combines the FreeStyle Libre 2 CGM with insulin pen smart caps to provide daily dose recommendations.
Participating in the Bigfoot Unity program requires an agreement between Bigfoot Biomedical and the health care provider. After establishing a contract, the prescribed Bigfoot supplies are delivered in a "one-stop-shop" directly to the patient's door each month. Information about the Bigfoot Unity program can be found on the Bigfoot Biomedical website.
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

Bigfoot Unity : Sensor
Sensor uses a thin, flexible filament inserted just under the skin to measure glucose levels every minute.
Bigfoot Unity : Controller
Smart cap displays dosing recommendations for manual insulin delivery through multiple daily injections.
Bigfoot Unity : Receiver
Smartcap is used to scan the sensor and displays dosage information directly on the screen and smart mobile device.
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.

Patient Considerations
Active Lifestyle
Light on body. Pens are easy to use and do not remain attached to the body, senor is light on the body.
Waterproof. The pump and CGM are waterproof and can be worn for most exercises.
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.
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
Many components. Have to carry pens, smart caps, pen needles, and CGM is attached to the body.
Shorter tubing option. A shorter 5-inch tubing option for comfort on body.
Easy Insulin Dosing
Dosing recommendations. Displays dosing recommendations and reminders for long-acting insulin.
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
Simple design. One-button device with easy to read display.
Easy Dosing. Full control from a smartphone, with the option to manually bolus if needed.
Fewer Fingersticks
Factory-calibrated sensor. Finger sticks needed for backup only.
Factory-calibrated sensor. Fingersticks needed for backup only.
Privacy
Hideable. Pens are portable but visible when in use. Frequent injections are unavoidable. Sensor is the smallest option available.
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.
