About EMAY
EMAY is a personal health-monitoring device maker that entered the Amazon marketplace in 2016 with its first portable EKG monitor and has grown into one of the most established independent EKG-monitor brands sold there, alongside AliveCor's Kardia line. The company says it has served more than 100,000 customers with heart-health concerns since launch. EMAY operates through two entities: Emay (HK) Limited, an engineering and product-development office in Wanchai, Hong Kong, and EMAY Inc, a US-based operation headquartered in Brighton, Colorado. A dedicated domestic customer-service team, built in 2019, handles support via toll-free phone, live chat, and email.
The product line centers on two categories: EKG monitors and pulse oximeters for home use. Its EKG monitors, including the 6-lead 6L Portable EKG Monitor and a pocket-sized single-lead model, record and store ECG traces without requiring a paired phone, and every device ships with unlimited PDF and CSV export at no subscription cost. The Sleep Oxygen Monitor line adds overnight SpO2 recording aimed at sleep-apnea screening conversations, exporting the same physician-ready reports. In our own testing, two EMAY EKG monitors and one EMAY sleep oximeter earned spots among our top picks.

Why we recognized EMAY
The BestRatedDocs Top Brand recognition isn't paid for and can't be applied for. We award it to the brands whose products consistently stand out in our category reviews. EMAY earned it on the strength of the products below, evaluated the same way every product on this site is: assessed against clinical criteria, verified specifications, and real-world user outcomes, and judged on merit.
