Dexcom G7
Medtronic Simplera Sync
Summary
Dexcom G7 is a low-profile, all-in-one glucose sensor/transmitter and warms up faster than other CGMs on the market. This sensor lasts for 10 days and sends real-time glucose readings to a compatible smartphone app or directly on an Apple Watch. No finger pricks or scanning is needed. Optional low and high-blood sugar notifications are available for this system.
FDA-approved for wear on the back of the upper arm for ages 2 years and older or the upper buttocks for ages 2-17.
MARD of 8.2%
This is a disposable, all-in-one CGM sensor integrated with Medtronic’s pump systems (e.g., MiniMed 780G). Typical wear time is 6 days, plus a 24-hour “grace period.” No routine fingersticks are required when the device is in closed-loop/SmartGuard mode.
FDA approved for ages 7+ on the back of the upper arm
MARD of ~9%
Components
Sensor
Sensor uses a thin, flexible filament inserted just under the skin to measure glucose levels every 5-minutes. Push-button applicator allows sensor to be placed on the body in one step.
Receiver
Conveniently access glucose readings using a reader, smartphone, or directly on an Apple Watch. Phone app available for both iOS and Android devices.
Sensor
Sensor uses a thin, flexible filament beneath the skin to continuously measure glucose every 5 minutes. Simple, one-step applicator makes insertion fast and easy.

Affordability and Access
$$$$
No insurance coverage data. Provided by DME and/or Pharmacy.
$$$$
Coverage depends on region and insurance; supplied via DME or specialty pharmacy.
Data Monitoring Options
Yes
Automatically and continuously sends data to the user’s Dexcom Clarity web-based cloud which is accessible by clinicians.
Yes
Data streams directly to the pump; users and clinicians can view trends and logs via Medtronic’s platforms.
Data View Options
Yes
Users must download the Dexcom G7 and Dexcom Clarity apps to view and share data. Both apps provide multiple data views, sharing options, and access through the clinician portal using a code from the user's device. Caregivers can use the Dexcom Follow app to view data.
Yes
Data view directly on your connected pump or smart device.
Duration and Storage
10 Days
Sensors last 10 days. They are shipped 3 boxes at a time every 3 months – 9 sensors. Works at 50ºF – 108ºF
6 Days
Sensors last 6 days, with a 24-hour grace period, and need about 2 hours to warm up. They work between 41°F – 104°F and should be stored between 36°F – 86°F. They are usually shipped in 1–3 month supplies, which is about 5–15 sensors at a time.

Patient Considerations
Active Lifestyle
Waterproof when submerged in 2.4 meters of water and must be within 20 (unobstructed) feet of the receiver or mobile device.
Compact and integrated. Reducing bulk; compatibility with daily activities depends on the adhesive and body movement. Water-resistant up to 8 feet (2.4 m) for 30 minutes.
Avoiding Highs and Lows
Custom alerts can be set for highs, lows, and rapidly rising or falling glucose levels. Trend arrows show the direction glucose is heading, with the rate of change.
SmartGuard closed-loop. Pump adjustments use sensor data continuously to reduce highs and lows.
Comfort
Low profile and low maintenance sensor application.
Low profile. No overtape needed and one-hand insertion.
Easy Insulin Dosing
Real-time data and alerts make dose adjustment easier.
SmartGuard technology. When paired with the MiniMed 780G, it automatically adjusts basal and gives correction boluses based on sensor readings. In manual mode, glucose values can guide dosing decisions, but fingersticks are required for confirmation.
Easy to Use
No scanning required. Readings are sent directly to the mobile app every 5 minutes.
All-in-one. Eliminates the need for a separate transmitter, simplifying sensor changes (although more frequent due to the 6-day wear).
Fewer Fingersticks
Factory-calibrated sensor. Finger sticks needed for backup only.
Calibration is optional. Perfect if you like having that choice.
Privacy
Quiet Mode (Vibrate). All system alerts will vibrate when this setting is enabled. Urgent Low Soon and technical alerts will sound if not acknowledged.
Small and integrated, but visible on the back of the arm. No separate transmitter reduces the number of visible parts. Alerts and alarms can be adjusted for discretion.
