Zio vs VisualDx

By the vendor's count, VisualDx holds more than 50,000 clinical images across skin tones and body sites behind a differential builder. Its history page lists HL7 infobutton and SMART on FHIR as 2012 milestones, and the homepage mentions EHR integration, single sign-on and API access, but no EHR is named. VisualDx states no FDA clearance, and a 2020 DermExpert FAQ says it is exempt from FDA regulation.

iRhythm holds 18 FDA 510(k) clearances dating from 2008, the latest for the ZEUS Platform on May 29, 2026. The vendor calls its deep-learned algorithm the first FDA-cleared one verified by qualified cardiac technicians and reports 99% physician agreement on end-of-wear reports. A clinician who wants an image-led differential buys VisualDx, and a health system ordering ambulatory ECG monitoring buys Zio. VisualDx cannot supply the second, and Zio supplies no differential.
