Medtronic Simplera Sync
Meter
Summary
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%
Good to have. Tried and true. Backup or day to day. Fingersticks required.
Components
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.
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.
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.
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.

Affordability and Access
$$$$
Coverage depends on region and insurance; supplied via DME or specialty pharmacy.
$$$$
Most accessible. Available over the counter at all Pharmacies. Price range; $0-$200/month depending on insurance coverage.
Data Monitoring Options
Yes
Data streams directly to the pump; users and clinicians can view trends and logs via Medtronic’s platforms.
Limited Options
Data is available directly on the device. Some meters may be compatible with the Tidepool data management system.
Data View Options
Yes
Data view directly on your connected pump or smart device.
Yes
Data may be viewed directly on the device. Some meters contain a built-in USB connection that allows information to be uploaded to a data management system.
Duration and Storage
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.
Daily
Meters can last several years with battery changes/charging, they're used daily and work between 65ºF-86°F
Vision / Auditory / Dexterity
YES text to speech
YES vibration alerts
Multiple sound sources
Moderate dexterity needed
NO text to speech
NO vibration alerts
A LOT of dexterity needed
Patient Considerations
Active Lifestyle
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.
Must pause activity to check blood sugar.
Avoiding Highs and Lows
SmartGuard closed-loop. Pump adjustments use sensor data continuously to reduce 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.
Comfort
Low profile. No overtape needed and one-hand insertion.
Meter supplies carried and requires visible blood.
Easy Insulin Dosing
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.
Limited features. No info on blood sugar trends.
Easy to Use
All-in-one. Eliminates the need for a separate transmitter, simplifying sensor changes (although more frequent due to the 6-day wear).
Large display. Device typically has large display numbers for easier readouts, and it's very simple to operate.
Fewer Fingersticks
Calibration is optional. Perfect if you like having that choice.
Frequent fingersticks are unavoidable.
Privacy
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.
No attached device for blood glucose monitoring.
