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
This sensor lasts the longest - 365 days. It has to be placed under the skin by a healthcare provider. It has two parts, the implantable sensor and a transmitter that sends data to a mobile device.
MARD: 8.5-9.1%
*Recently FDA approved for use with insulin pumps.
Components
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.
Eversense : Sensor
Professionally inserted by a physician during a medical visit. Minor procedure.
Eversense : Transmitter
Transmitter sits outside of the body and is held on by an adhesive. Sends data every 5 minutes to a connected mobile device.
Eversense : Receiver
Real-time glucose measurements sent to a compatible mobile-device or smart watch. No need for a separate receiver. Available for both iOS and Android devices.
Device Details
Overview
Tandem Mobi is the smallest insulin delivery system to be fully controlled by a smartphone.
Very small implantable sensor but large transmitter must be worn on top of the skin.
Affordability and Access
$$$$
Pump coverage is not yet available. Sensor is widely covered and provided by DME and/or Pharmacy. Sensor price range; $0-$500/month.
$$$$
Sometimes covered. Insertion and removal require a Health Care Provider. Insertion costs $100-$300, and removal costs $100-$400. Sensor and transmitter cost $800-$1400.
Data Monitoring Options
Yes
The t:connect mobile app for the t:slim X2 pump wirelessly uploads pump and CGM data to the cloud-based t:connect web application.
Yes
CGM data can upload automatically to the web-based Eversense data management system (EDMS) from the Eversense mobile app.
Data View Options
Yes
Data can be viewed directly on the pump screen or on the t:connect mobile app (available for both iOS and Android devices).
Yes
Eversense mobile app receives and displays data in easy-to-read charts and graphs that can be shared with family and friends through the Eversense NOW app.
Duration and Storage
3-day pump 10-day sensor
Sensors last 10 days and transmitters last 90 and work at 50ºF – 108ºF. Pump can be used for up to 72 hrs, battery life lasts five days with the use of CGM, and work between 40°F - 99°F. Pump supports wireless charging.
365 Days
Sensor lasts 365 days, but a physician must implant it. Transmitter must be charged daily.
Vision / Auditory / Dexterity

Patient Considerations
Active Lifestyle
Waterproof. The pump and CGM are waterproof and can be worn for most exercises.
Water-resistant transmitter when submerged in 1 meter of water for up to 30 minutes and must be within 25 feet of the connected smart 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.
On-body vibration alerts when blood glucose levels are higher or lower than the set range. 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.
Longest-lasting sensor fits comfortably under the skin. Minor procedure is required. Least likely to have compression lows.
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.
Predictive alerts make insulin dosing easier by tracking high and low trends.
Easy to Use
Easy Dosing. Full control from a smartphone, with the option to manually bolus if needed.
Minor procedure. Requires insertion by a physician during a medical visit.
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. Tiny sensor is implanted under the skin, so the user can be discreet when needed. Ability to see sugar on watch or phone. Sensor not movable on body and requires regular meter use.
