Multi-Frontend

Deliver surveys via Telegram Bot or Progressive Web App. The same survey engine powers both frontends through a unified channel abstraction.

Flexible Surveys

Define surveys in YAML with support for Likert scales, multiple choice, free text, photos, voice, cognitive assessments, and conditional branching.

Wearable Integration

Collect physiological data from Fitbit, Oura, and Withings via webhooks and daily sync. Trigger surveys based on real-time health events.
