Open mHealth is a nonprofit, community-driven initiative that develops open standards and open-source software for making patient-generated health data interoperable across mobile apps, wearables, clinical systems, and electronic health records. Its core contribution is a library of clinically validated JSON Schema data point schemas — covering physical activity, sleep, heart rate, blood pressure, body weight, blood glucose, and other vital signs — with the sleep, physical-activity, and metadata schemas now superseded by IEEE 1752.1, the IEEE standard for Mobile Health Data co-shepherded by the Open mHealth community. Around the schemas Open mHealth ships a stack of Apache-2.0 reference implementations: Shimmer (a Java/Spring server that pulls health data from Fitbit, Google Fit, iHealth, Misfit, RunKeeper, and Withings APIs and normalizes it into Open mHealth or IEEE 1752.1 data points), omh-dsu-ri (a Data Storage Unit reference implementation exposing an OAuth 2.0-secured Data Point REST API on top of MongoDB and PostgreSQL), Granola (an Objective-C library that serializes Apple HealthKit samples into Open mHealth JSON), a web visualizations library built on D3 and Plottable.js, the OMH-on-FHIR mapping that aligns Open mHealth data points to HL7 FHIR resources, and a sample-data-generator. Open mHealth operates as the steward of the standard, the schema and unit registry at registry.openmhealth.org, and a developer community of thousands of developers and health organizations including Cornell Tech, Kaiser Permanente, Stanford School of Medicine, UC Davis, and UCSF. The project has no commercial API, no paid tier, and no hosted SaaS — all artifacts are open source under Apache 2.0 and the standard itself is openly published.
