Metricwire

Metricwire is a real-world data collection platform for ecological momentary assessment (EMA), experience sampling (ESM), and digital-health research. It helps organizations measure real-world experiences to inform treatments, service offerings, and policies. Researchers design studies, schedule time- and event-based prompts, collect participant self-reports alongside passive sensor and wearable data through native iOS and Android apps, and export the results for analysis. The platform is used across clinical trials, behavioral and public-health research, and patient-reported outcome programs, with an emphasis on data privacy and security (ISO 27001, GDPR). A production JSON API is served from api.metricwire.com and a participant/researcher application from app.metricwire.com, though Metricwire does not currently publish an open developer portal or machine-readable API specification.

Metricwire publishes 1 API on the APIs.io network. Tagged areas include Company, Research, Data Collection, Ecological Momentary Assessment, and Experience Sampling.

Metricwire’s developer surface includes support and 10 more developer resources.
