ONDA Delivers a 90 day supply of sensors to your door

The FreeStyle Libre 3 Plus provides real-time glucose readings every minute without the need for scanning. Only slightly larger than a penny, the sensor is worn on the upper arm, lasting up to 15 days. The system transmits data automatically to a compatible smartphone or reader, allowing users to track glucose trends and receive alerts for high or low blood sugar levels.

The FreeStyle Libre 3 Plus offers high accuracy compared to previous models, with a low mean absolute relative difference (MARD). It does not require routine fingerstick calibrations and integrates with digital health platforms for remote monitoring. The device is covered by many insurance plans, including Medicare for eligible patients, making it an accessible option for continuous glucose monitoring.

The Dexcom G7 provides real-time glucose readings every 5 minutes, transmitting data automatically to a smartphone or receiver. The sensor is about the size of a nickel, and lasts up to 10 days with a 12-hour grace period for replacements. It features built-in alerts for high and low glucose levels and does not require routine fingerstick calibrations.

Compared to the FreeStyle Libre 3 and 3 Plus, the Dexcom G7 has a shorter wear time (10 vs. 14-15 days) but offers stronger integration with insulin pumps and other diabetes management platforms. It is known for high accuracy (low MARD) and customizable alerts, making it a preferred option for users needing frequent glucose updates and pump compatibility.

Compared to the FreeStyle Libre 3 Plus, the standard Libre 3 has a shorter sensor wear time (14 vs. 15 days). 

Both models provide real-time glucose tracking without scanning, transmit glucose trends to a smartphone or reader and integrate with digital health platforms for remote monitoring.

Compared to the Dexcom G7, the G6 has a larger sensor and separate transmitter that must be reused across multiple sensors. 

It also has a longer warm-up time (2 hours vs. 30 minutes for G7) and no built-in grace period for sensor changes. However, it remains a widely used CGM with strong insulin pump integration.

The FreeStyle Libre 2 provides glucose readings every minute but does not transmit real-time glucose data automaticatlly and requires users to scan the sensor with a reader or smartphone to view data. The sensor lasts up to 14 days and offers optional glucose alarms for high and low readings.

Compared to the Libre 3 and 3 Plus, the Libre 2 has a larger sensor size, about the size of two stacked quarters. It also has a higher MARD, meaning slightly lower accuracy. 

While the 14-Day Reader has been discontinued, the original Freestyle Libre system continues to be supported.

Abbott, the manufacturer, no longer distributes the 14-Day Readers, but they will be grandfathering the old users by continuing to provide sensors. As long as your reader still works with the 14-day sensors, you can continue to use it.
