*Problem* Apple Health on iPhone locks raw data behind an XML export that’s 100 MB+ and painful to parse. I wanted a programmatic, privacy-friendly way to feed that data into notebooks and LLMs.

*Solution* HLExport (SwiftUI): * Reads every HealthKit type between any start/end date * Outputs compact JSON (share sheet or clipboard) * 7-level mood logger (`HKCategoryTypeIdentifier.stateOfMind`) * All on-device; no backend; MIT-licensed

Under 600 KB binary size. iOS 17+ (mood write: iOS 18). Happy to answer questions & take suggestions – this is weekend-project code that I’d like to harden with your feedback.
