Open mHealth
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body weight, blood glucose, and other vital signs — with the sleep, physical-activity, and metadata schemas now superseded by IEEE 1752.1, the IEEE standard for Mobile Health Data co-shepherded by the Open mHealth community.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.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
API Evangelist profiles Open mHealth the way a machine reads it — 1 machine-readable artifact, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Open mHealth scores 10.1/100 (minimal), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.
How we profile Open mHealth
Each block below is one kind of artifact we hold for Open mHealth. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
Security Posture 1
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
