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.

Regulatory Posture applies to this provider. Its tags matched the Health regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/metricwire: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
