What does the accuracy figure mean?
MARD is the average gap between what the sensor says and what a laboratory blood test says, as a percentage. A 10% MARD means readings are off by about 10% on average — so a true 7.0 mmol/L might show as anywhere around 6.3 to 7.7. Lower is better. Most current sensors sit under 10%; twenty years ago they were over 20%. No sensor is exact, which is why treatment decisions still get confirmed with a fingerstick when a reading does not match how you feel.

What works well
- Disposable all-in-one sensor with a two-step insertion and no overtape to apply
- Readings on an Apple Watch as well as a phone
- The Sync version drives the MiniMed 780G closed loop, which no other sensor here does
What to watch out for
- Seven-day wear — the shortest here, meaning roughly 52 sensors a year
- Two-hour warm-up, four times the Dexcom G7
- Mainly bought as part of a Medtronic pump system rather than on its own
Our verdict
The sensor to look at if you use or want a MiniMed 780G pump, because that integration is the reason it exists. As a standalone sensor the seven-day wear and two-hour warm-up make it hard to recommend over the alternatives.
Common questions
- How long does a Medtronic Simplera sensor last?
- 7 days, after a two-hour warm-up.
- What is the difference between Simplera and Simplera Sync?
- Simplera Sync is the version that talks to the MiniMed 780G pump for automated insulin delivery. Plain Simplera sends readings to the phone app.
