Apple describes three "modules" available within ResearchKit, including Surveys, Informed Consent and Active Tasks.
ResearchKit provides a standardized interface to quickly build surveys. These modules are already localized. This would work for the majority of current research use cases.
One of the most significant inclusions is native informed consent capability, as you may have seen in the keynote:
- Motor Activities
- Gait, tapping
- 6-minute walk
- Spatial memory
