Meter
Medtronic Simplera Sync
Summary
Good to have. Tried and true. Backup or day to day. Fingersticks required.
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
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.
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
$$$$
Most accessible. Available over the counter at all Pharmacies. Price range; $0-$200/month depending on insurance coverage.
$$$$
Coverage depends on region and insurance; supplied via DME or specialty pharmacy.
Data Monitoring Options
Limited Options
Data is available directly on the device. Some meters may be compatible with the Tidepool data management system.
Yes
Data streams directly to the pump; users and clinicians can view trends and logs via Medtronic’s platforms.
Data View Options
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.
Yes
Data view directly on your connected pump or smart device.
Duration and Storage
Daily
Meters can last several years with battery changes/charging, they're used daily and work between 65ºF-86°F
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.
Vision / Auditory / Dexterity
NO text to speech
NO vibration alerts
A LOT of dexterity needed
YES text to speech

Multiple sound sources
Moderate dexterity needed
Patient Considerations
Active Lifestyle
Must pause activity to check blood sugar.
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
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.
SmartGuard closed-loop. Pump adjustments use sensor data continuously to reduce highs and lows.
Comfort
Meter supplies carried and requires visible blood.
Low profile. No overtape needed and one-hand insertion.
Easy Insulin Dosing
Limited features. No info on blood sugar trends.
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
Large display. Device typically has large display numbers for easier readouts, and it's very simple to operate.
All-in-one. Eliminates the need for a separate transmitter, simplifying sensor changes (although more frequent due to the 6-day wear).
Fewer Fingersticks
Frequent fingersticks are unavoidable.
Calibration is optional. Perfect if you like having that choice.
Privacy
No attached device for blood glucose monitoring.
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.
