Palo Alto, California-based MocaCare, which has developed a device that tracks cardiovascular health, raised $2 million in a round led by JDM Mobile Internet Solutions with participation from EMB International and Atom Health Corporation. This brings the company's total funding to $4 million to date.

The device, called MocaHeart, scans the user's fingertips to measure blood flow velocity and uses that metric to determine heart rate and blood oxygen levels. It also offers users a qualitative measure of users' overall cardiovascular health, called the Moca Index, which the company says is correlated to blood pressure. 

Use cases for MocaHeart include consumers who want to track fitness, those who have a heart condition and need to track their heart daily, people with high blood pressure, and consumers who want to make sure loved ones are in good health. The companion app allows users tracking their health to send measurements to caregivers or family members. Users can view their data in graphs of hourly, daily, weekly, and monthly trends. The app also reminds the user to take readings and go to doctor appointments.

The devices are expected to ship in September 2015 and are priced at $149.99.

MocaCare Cofounder and Chief Operating Officer Naama Stauber told MobiHealthNews that MocaCare will use the funds for growth in North America and China -- thanks to help from new strategic investor JDM Mobile Internet Solutions, which specializes in bringing products to China from North America. While she said they don't plan to seek FDA clearance for this device, they are planning to do so for the next generation of MocaHeart, which the company plans to launch next fall.

Stauber added that they are also developing other health tracking devices. One such device will track cholesterol and two others will focus on pediatrics and elder care.

At the end of last year, MocaCare launched a crowdfunding campaign for MocaHeart, which raised $120,723.
