Best CGM Value — 14-Day Wear + Continuous No-Scan
| Type | CGM (14-day sensor) |
| Wear time | 14 days |
| Low alarm | Yes |
| High alarm | With Libre 3 Plus update |
| Prescription | Required |
The Abbott FreeStyle Libre 3 is the thinnest CGM sensor available — coin-sized, 14-day wear, and continuous automatic readings sent to the LibreLink app every minute. Unlike the original Libre 1 which required manual scanning, the Libre 3 provides continuous automatic monitoring with low glucose alarms. FDA cleared for insulin dosing without fingerstick confirmation in most clinical scenarios. Often less expensive than Dexcom with comparable accuracy.
