Build a Clinician-Grade HealthKit Cardiac Rehab iOS App. Advanced challenge in code. Writing production code that solves real engineering problems, earn a bl...
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 privacy posture that survives a Series B legal review.
This is not a coding exercise. It is the work a software engineer does between a Jira ticket and a merged PR. That distinction matters to every hiring manager who has seen candidates solve LeetCode problems and none who have shipped production code under real constraints.
When you finish, you will have something most graduates do not: a real-world deliverable, verified by Ewance, that you can show to a hiring manager and say "I did this. Here is the proof."
Earning criteria — what you'll demonstrate
- Request and justify minimal HealthKit read scopes and reliably reconcile data deltas across relaunches and sync gaps
- Translate a written clinical rule specification into deterministic, testable on-device logic with explicit safety boundaries
- Implement a TLS certificate-pinned network sync conforming to a fixed JSON contract
- Author a privacy posture that withstands medical-device-grade legal review
- Plan and report a small-cohort usability study that surfaces real adherence and friction honestly

Careers
Career paths this challenge builds toward
Completing this challenge demonstrates skills that transfer directly to these roles:
Health iOS Engineer
This challenge mirrors regulated digital-health iOS work end to end: integrating HealthKit sensor data, building on-device clinical logic, and shipping through TestFlight under a medical-device pathway—the exact portfolio a digital therapeutics team screens for.

Mobile Privacy Engineer
Authoring a defensible data-minimization and deletion posture alongside a TLS-pinned sync builds the privacy-by-design and secure-networking judgment that mobile teams handling sensitive health data require before a Series B audit.

Sensor Integration Engineer
Reconciling wearable heart-health streams across relaunches and sync gaps, then driving deterministic on-device logic from them, develops the real-time sensor-data engineering skill wearable and IoT-health companies hire for.
