Native iOS HealthKit Integration for a Cardiac Rehab Startup
Overview
What this challenge is about.
Build a SwiftUI app targeting iOS 17+ that requests HealthKit read scopes (heart rate, HRV, resting HR, workouts), reads the last 7 days on launch and subscribes to live updates. Run an on-device exercise-prescription rule engine (3 named rules) that produces a daily plan and flags safety boundaries. Sync a daily clinician summary JSON to a mock cloud endpoint with TLS-pinned URLSession. Recruit 6 testers via TestFlight, run a 2-week diary study. Deliver: TestFlight build + repo, 8-page privacy/permissions document (data minimization, scope justification, deletion), 6-page usability study.
The Brief
What you'll do, and what you'll demonstrate.
Ship an iOS HealthKit-integrated cardiac-rehab prototype with on-device prescription logic, a TLS-pinned cloud sync, and a defensible privacy document.
Earning criteria — what you'll demonstrate
- Request and manage HealthKit scopes with data minimization
- Implement on-device clinical logic that fails safely on missing data
- Pin TLS and design the smallest possible payload for clinician sync
- Write a privacy document that survives a Series B due diligence
