Mobile-first cognitive assessment for modern clinical research

An open-source platform that delivers validated cognitive batteries to participants on iOS, Android, or the web — with offline support, REDCap integration, and 21 CFR Part 11 audit trails built in. Designed for decentralized trials, multi-site studies, and academic research teams.

Metricis researcher portal dashboard, showing study management, registries, and the module library

Researcher portal — study management, registries, and the cognitive module library.

Why Metricis

Modern clinical trials increasingly need cognitive endpoints — but the tools haven’t kept up. Validated batteries are stuck on lab desktops. EDC systems can’t deliver interactive tasks. Custom builds take a year of engineering and still won’t ship to participants’ phones.

Metricis closes the gap: it pairs a jsPsych-based cognitive battery with full electronic data capture, mobile delivery, and the regulatory infrastructure clinical research demands.

What Metricis does

A research-ready platform you can adopt or adapt — open from end to end.

Mobile-first delivery

Native iOS and Android apps built with Capacitor deliver assessments on participants’ own devices. Offline-capable for studies in low-connectivity settings; auto-syncs when reconnected.

jsPsych task battery

Built on jsPsych — the most widely-used open-source platform for behavioral and cognitive experiments. Ships with CPT, n-back, Flanker, Trail-Making, simple reaction time, PROMIS measures, and computerized adaptive testing.

Native REDCap integration

Already running your study on REDCap? Metricis acts as a delivery layer — assessments score automatically and post results to existing REDCap forms. Multi-site routing, event-aware scheduling, webhook-driven sync.

Built-in electronic data capture

For standalone studies, Metricis includes a full ODM-compatible EDC: form designer, validation rules, edit checks, query workflow, source data verification, and an immutable form workflow state machine.

Compliance by design

21 CFR Part 11 e-signatures with reason-for-change capture. SHA-256 audit hash chain verified nightly. HIPAA-aware PII redaction in logs. Encryption at rest for tokens. Consent enforcement at the service layer — not just the UI.

Bilingual and multi-site

English and French interfaces. Per-study consent, scheduling, and notification policies. Site-aware REDCap routing for multi-centre trials.

Compliance & trust

Designed for the regulatory and institutional review your study has to pass.

21 CFR Part 11: Electronic records and signatures with reason-for-change capture, immutable audit log, role-gated state transitions.
ICH E6(R2) GCP: Coordinator review, source data verification, query and reconciliation workflow, data lock.
HIPAA-aware: PII redaction in logs (email, SSN, phone, MRN, DOB), role-based access enforced at the service layer, encryption at rest for credentials.
Audit integrity: Every audit log entry chained by SHA-256 over (previous_hash + action + entity + timestamp + user); chain verified nightly in CI.
Open source: MIT licensed; full source available for institutional security and compliance review.
University of Alberta: Built and maintained at the University of Alberta — institutional academic stewardship.
