Dexcom G7 vs Freestyle Libre 3: The Ultimate Comparison for Smart Diabetes Management

Dexcom G7 vs Freestyle Libre 3: The Ultimate Comparison for Smart Diabetes Management

Managing diabetes has come a long way from fingersticks and logbooks. With Continuous Glucose Monitors (CGMs), patients now enjoy real-time glucose tracking, trend analysis, and better control over their health.

Among the most popular options available today, the Dexcom G7 and Freestyle Libre 3 stand out as top contenders. But which one is the right fit for you? Let’s explore how they compare — and how EZ DME Solutions makes getting them easier through DME insurance coverage.

1. Overview: Dexcom G7 vs Freestyle Libre 3

Both devices are designed for continuous glucose monitoring without fingersticks, but their technology and user experience differ slightly.

• Dexcom G7: Known for high accuracy, customizable alerts, and direct integration with insulin pumps like the Tandem t:slim X2.
• Freestyle Libre 3: Renowned for being the smallest CGM sensor available, offering real-time readings directly to your smartphone.

Both systems help users stay in their Time in Range (TIR) and reduce hypoglycemic events, which are essential for long-term diabetes management.

2. Key Differences Between Dexcom G7 and Freestyle Libre 3

Here’s a quick breakdown of how these two devices compare:

Feature Dexcom G7 Freestyle Libre 3
Sensor Size Compact and rounded Smallest CGM available
Wear Duration 10 days 14 days
Warm-Up Time 30 minutes 60 minutes
Calibration Needed No No
Alerts Customizable high/low alerts Optional real-time alerts
Data Sharing Up to 10 people Up to 20 people
Integration Works with Tandem t:slim X2, Apple Watch Works with LibreLink app
App Compatibility Android, iOS Android, iOS
Water Resistance Up to 8 feet, 24 hours Up to 3 feet, 30 minutes

If your goal is seamless insulin pump integration and quick alerts, Dexcom G7 wins. But if you prefer a minimalist sensor with longer wear and simplicity, the Freestyle Libre 3 is an excellent choice.

3. Accuracy and Reliability

Accuracy is crucial for any CGM. The Dexcom G7 features one of the lowest MARD (Mean Absolute Relative Difference) scores — a measure of accuracy — at approximately 8.2%.

The Freestyle Libre 3 is also extremely precise, with a MARD of around 9.2%, meeting global accuracy standards.

Both provide data you can trust to make real-time insulin or dietary adjustments.

According to the National Institutes of Health (NIH), accurate CGM readings reduce A1C levels and improve glucose control without increasing hypoglycemia risk.

4. Ease of Use

The Dexcom G7 and Freestyle Libre 3 are both designed with user convenience in mind:

Dexcom G7: Auto-applicator makes sensor insertion quick and painless. Real-time readings appear directly on your smartphone or smartwatch.

Freestyle Libre 3: Uses a smaller sensor and a simple insertion device. Once applied, it works quietly in the background, sending readings every minute.

Both systems automatically track your glucose trends, so you can make better food and medication choices throughout the day.
