Redwood, California-based health app maker Hello Heart has raised $1.3 million in a round led by Resolute Ventures with participation from angel investors including Waze CEO Noam Bardin, BlueRun ventures Co-founder John Malloy, and Facebook Product Director Ran Makavy.

“We set out to do one thing -- make it simple, painless, and even fun to track and understand your medical data," Hello Heart CEO Maayan Cohen said in a statement. "Most people are worried about their health but struggle to collect and understand all the numbers and readings. In fact, 50 percent of Americans are unable to understand if a simple out-of-range result in their lab reports is good or bad. We change that.”

Hello Heart, available only on iOS devices for now, helps patients aggregate and make sense of their lab data after pulling it from the various medical records it's stored in. The app helps users find their lab data by searching for all of their providers from a preloaded list, for example Cleveland Clinic, Cincinnati Children's, and Community Health Network. 

Users then authorize the data transfer by logging into their patient portals at the various providers. From there, Hello Heart helps patients make sense of their data. For example, the app will help patients understand their diabetes risk, hypertension level, and cholesterol levels. The company said the app is already integrated with health records systems that are used by more than 50 percent of US hospitals and clinics.

The app also allows users to manually enter their blood pressure data or sync the data from connected blood pressure monitors via Apple's data exchange HealthKit.

Hello Heart displays this data on a dashboard in the app and also provides users with insights and explanations about their blood pressure readings -- the insights are based on information from sources like the CDC and the American Heart Association. Users can also choose to set reminders to check their blood pressure readings periodically.

The company also plans to launch an Apple Watch app shortly after the smartwatch launches.
