Problem
Average users can have rich Apple Health data without a clear, calm explanation of what changed or whether enough data exists to trust a pattern.
Solution
PlainHealth reads approved HealthKit data locally, summarizes it in plain English, explains missing data and confidence, and keeps privacy and deletion controls visible without Premium.
Outcome
The product demonstrates privacy-first iOS delivery across HealthKit permissions, local summary generation, App Store support URLs, subscription surfaces, widgets, and non-diagnostic wellness copy.
