Open mHealth

Every day, more cell phone apps are created for finding health information, and tracking and sharing health data with our health care providers. These mobile health (mHealth) apps are becoming more popular—with one in five smartphone users now having a health app, according to Pew Internet. However, many of these apps are not built in an open-source way that allows easier data-sharing across platforms or collects data as useful guides for patients and providers, such as allowing physicians to track a patient’s symptoms between appointments.

To break down barriers between health and technology, RWJF supports Open mHealth, a nonprofit startup that's bringing clinical meaning to the explosion of digital health data. Open mHealth does this by collaborating with clinical experts to make health data useful and actionable for patients and clinicians, helping developers integrate disparate digital health data into the clinical environment with an open API platform, and building patient-centered products that support personalized, proactive health care.

An Open Architecture to Improve Individual- and Population-Level Health

Open approaches have accelerated innovation in many fields—including the creation of the Internet—and can similarly advance the mHealth field. By fostering an open architecture and encouraging developers and health innovators to collaborate, Open mHealth is promoting industry-wide cooperation and growth, rather than siloed technologies and competition, to create more effective mHealth apps.
