Program Overview

The Circular Affiliate Program brings publishers into the fast-growing smart-ring and health-tracking space. Circular's Ring 2 ($349) is the world's first ECG smart ring: a 40-second single-lead ECG screened for atrial fibrillation, blood-pressure trend readings from the finger, four-stage sleep tracking, HRV-based recovery, stress monitoring, women's cycle insights, and the Kira AI health coach — 140+ biomarkers read from a 4-gram titanium ring with a 7-day battery. Unlike most wearables, there is no mandatory subscription: all core health tools are included with the one-time purchase. With 10+ industry awards, coverage from major tech and health press, and a $349 price point, Circular converts health-conscious buyers. Publishers earn 5%–10% commission on referred sales, deep linking is allowed so you can point straight at the ring or specific feature pages, and joining runs through affne.com.
