-
Track glucose trends throughout the day and night
-
Receive alerts for high or low glucose levels
-
Share data with caregivers or healthcare providers
-
Reduce reliance on finger-prick tests
Choosing the right CGM balances accuracy, comfort, usability, features, and cost.

In-Depth Comparison Details
Sensor Size & User Comfort
Linx CGM’s sensor stands out for its small size and light weight. Users find it more comfortable for everyday wear compared to the larger and thicker Dexcom and older FreeStyle Libre sensors. The small profile reduces device visibility, improving discretion.
Accuracy & Calibration
-
Dexcom devices, particularly the G7, excel with industry-leading MARD (Mean Absolute Relative Difference) accuracy approximating 8.7%, requiring no finger-stick calibration.
-
Linx CGM offers a strong 9.8% MARD in adults, combining factory calibration with optional manual calibration for those seeking tailored precision.
-
FreeStyle Libre 2 and 3 provide accuracy comparable to Dexcom but differ with Libre 2 requiring scanning to get glucose data.
Alerts and Safety Features
Linx CGM provides reliable customizable low and high glucose alerts, including urgent low alerts fixed at 3.0 mmol/L to enhance user safety. Dexcom G7 and ONE+ have predictive low glucose alarms and delayed high glucose alerts for proactive management. FreeStyle Libre 2 lags with no urgent low alert, while Libre 3 shows improvements but lacks the comprehensive alerts Dexcom and Linx CGM offer.
Wear Duration and Cost
Linx CGM offers a 15-day sensor life, aligning with Dexcom ONE+ and Libre 3 but exceeding Dexcom G7’s 10-day wear. Linx CGM generally costs less than Dexcom devices, providing an affordable alternative without sacrificing key features.
Remote Data Sharing & App Ecosystem
All systems provide smartphone apps for data viewing and management. Linx CGM uploads data continuously to its PanCares diabetes management platform, enabling caregivers and clinicians to access up-to-date glucose info. Dexcom uses Clarity and Follow apps with broad integration. FreeStyle Libre apps offer sharing but with some limitations tied to scanning requirements.
