Wearable Health Devices to Watch: H2Wearable Health Devices to Watch: H2

South Korea-based H2 Care has developed the H2, a small, lightweight, wrist-worn blood pressure monitor that lets users get readings from anywhere in 20 seconds. The device is paired with an online dashboard for managing the data it captures, and a companion app can be set to remind users to take readings at set intervals. The company raised more than $50,000 via an Indigogo crowdfunding campaign in 2014.
