A key Apple Watch health feature just got a landmark stamp of approval

The Apple Watch's atrial fibrillation (AFib) history feature has received approval from the U.S. Food and Drug Administration (FDA) as a Medical Device Development Tool (MDDT). This certification allows the feature on Apple Watch Series 4 and later to be used in clinical trials to verify other medical devices. This marks the first time a digital health technology has been approved for MDDT use by the FDA. The approval underscores the Apple Watch's growing credibility as a health and fitness tracker.
