This app will help site users collect information from participants by guiding them through a series of questionnaires for each visit.
Regarding our usage of the HealthKit API: We use Apples ResearchKit library to gather information from participants throughout their participation in the study. We do not use any HealthKit functionality for this study, but it is not possible to remove the HealthKit APIs from Apples ResearchKit library. For more information on the library, see https://developer.apple.com/researchkit/.
