> How to compare glucose sensors: accuracy, wear time, real-time or scan, and what you do with the data. With notes for Indonesia.

Most "best CGM" lists compare brand names. A better way is to compare what matters to you: how accurate the sensor is, how long it lasts, how it gets data to your phone, and what the app does with it.

|  | FreeStyle Libre 2 Plus | Dexcom G7 15 Day | LinX |
| --- | --- | --- | --- |
| Reads every | 1 minute | 5 minutes | 1 minute |
| Wear time | 15 days | About 15 days | 15 days |
| Real-time or scan | Real-time | Real-time | [CONFIRM] |
| Sold in Indonesia | 5 minutes | 5 minutes | Yes, from A1C |
| Price in Indonesia | 5 minutes | 5 minutes | About Rp1,5 juta for one sensor [CONFIRM] |

## What is a CGM?

A continuous glucose monitor (CGM) is a small sensor worn on the body. It reads glucose in the fluid under the skin and sends the result to your phone. You do not need diabetes to wear one, but most products and most research were built for people who have it.

## What should you compare?

**1. Accuracy.** Accuracy is reported as MARD, the average gap between the sensor and a lab reference. Lower is better. Leading sensors now reach about 8 to 10 percent. Ask for the study behind any number, and who was in it.

**2. Real-time or scan.** A real-time sensor sends readings on its own and can alert you. A scan sensor shows a reading only when you hold your phone or reader to it. Real-time is easier to learn from, because the curve fills in while you live your day.

**3. Reading rate and wear time.** Some sensors read every minute, some every five. A faster rate shows a quick rise after a meal more clearly. Wear time differs by sensor, so check it, because a longer wear means fewer sensors to buy. Wear days per model are listed below.

**4. What happens to the data.** A sensor shows a line. The app decides whether you understand it. Check what the app does with sleep, food and activity, and whether it explains the pattern.

## Which sensors may you see in Indonesia?

Specs below come from each maker's page, checked on 2026-10-31. Availability and prices change often, so we do not list them. Ask the maker or an authorised seller.

- **FreeStyle Libre (Abbott).** The Libre 2 Plus reads every minute and lasts 15 days. Ask the maker or an authorised seller whether it is sold in Indonesia, and at what price.
- **Dexcom G7.** The G7 15 Day is real-time and lasts about 15 days. Ask the maker or an authorised seller whether it is sold in Indonesia, and at what price.
- **LinX.** The sensor in the A1C CGM program. One reading a minute. It is worn for 15 days. The price is about Rp1,5 juta for one sensor from A1C. [CONFIRM: live store price.] [CONFIRM: regulatory wording, exact AKL or Kemenkes line.]

## Two limits that apply to all of them

- **A sensor trails your blood by minutes.** It reads fluid, not blood, so after a meal or a hard session it can differ from a finger prick. Use the trend, and use a finger prick if a reading does not match how you feel.
- **There is no agreed "healthy range" for people without diabetes.** Targets you see in apps come from diabetes guidance. Read them as a rough guide to your own patterns.

## Cost and access

Access and price vary a lot between countries and stores. Buy from the maker or an authorised seller. Marketplace listings can carry the wrong sensor type or an expired one.

## Which one fits you?

- If you want to try a sensor for a short run and read the curve alone, any sensor with a simple app can work.
- If you want the curve read next to sleep, activity and food, with an AI to ask, choose the sensor that works with an app that does that. A1C Insights works with LinX and reads Apple Health and Health Connect.

A1C Insights is an app, not a medical device. Talk to your doctor before you use a sensor if you take medicine for blood sugar.

## What you still control

Whichever sensor you pick, wear it for one full cycle. Then pick one habit to change and compare the next cycle.

## Frequently asked questions

### Can you wear a CGM without diabetes?

Yes. You do not need diabetes to wear one, but most products and most research were built for people who have it. If you take medicine for blood sugar, talk to your doctor before you use a sensor.

### What should I compare when choosing a CGM?

Four things: accuracy, whether it is real-time or scan, reading rate and wear time, and what the app does with the data.

### What is MARD?

MARD is the average gap between the sensor and a lab reference. Lower is better. Leading sensors now reach about 8 to 10 percent. Ask for the study behind any number, and who was in it.

### Is there a healthy range for people without diabetes?

No agreed range yet. Targets you see in apps come from diabetes guidance, so read them as a rough guide to your own patterns.
