## What it is
ResearchKit is an open-source framework for building iOS apps for medical and other research studies. It provides pre-built UI modules for informed consent, surveys, and sensor-based active tasks.

## Use cases
- build an app for a medical research study
- collect informed consent with on-device signatures
- create surveys and questionnaires for study participants
- capture sensor data from active tasks like fitness and cognition tests
- enroll study participants at scale via iPhone apps
- build a digital health study app on iOS

## When to choose
- you are building an iOS app for clinical or medical research
- you need standardized consent, survey, and active-task modules
- you want a proven framework used by large-scale research studies

## When to avoid
- you target Android or cross-platform only
- you need a non-Apple ecosystem or web-based study platform
- your app is not research- or care-related

## Facets
