Health Export Kit vs RingLedger

Health Export Kit turns your Apple Health data into portable files you actually own. Pick the categories you want — sleep, activity, workouts, heart rate, HRV, blood oxygen, respiratory rate, Apple Watch wrist temperature, steps, energy, exercise minutes, distance, flights climbed. Pick a date range. Pick Markdown or JSON. Tap Export. You get a clean, human-readable file that's ready for Files, iCloud Drive, AirDrop, email, spreadsheets, or pasting into an LLM for analysis. Everything runs on-device. — No account. No sign-in. No cloud. — No analytics. No advertising. No tracking. — No third-party SDKs. — No network requests, ever. Your Health data never leaves your iPhone unless you decide to share the file, and you choose exactly where it goes. Why Markdown and JSON? — Markdown is token-efficient and designed to paste into LLMs that need your context. — JSON is clean, compact, and built for spreadsheets and custom pipelines. What's inside an export: — Sleep: sessions, stages, duration, efficiency, per-stage averages for heart rate, HRV, respiration, SpO2, and wrist temperature; plus full per-minute streams if you want them. — Activity: daily summaries for steps, active energy, exercise minutes, walking/running distance, flights climbed. — Workouts: detailed sessions with heart rate, power, cadence, distance, splits, events, and routes (when your Apple Watch captured them). Designed for people who: — want a local backup of their Health data they can keep forever. — want to feed their own data into an LLM instead of handing it to a third-party service. — want spreadsheet-ready rows without wrangling a 2 GB XML export from apple.com. — simply want to own their data. Requires iOS 17+ and HealthKit. iPhone only.

RingLedger is an independent companion for compatible smart rings, including select Oura Ring models. It connects over Bluetooth, stores a private ring key on-device, syncs sleep and activity records to your personal dashboard namespace, and shows recent scores, sleep intervals, movement blocks, and daily details. First-time setup requires a factory-reset compatible ring. Before pairing, use the manufacturer's app to run a final sync so your historical account data is backed up, then reset the ring and forget it in iPhone Bluetooth settings. RingLedger estimates wellness scores from the data available through direct ring sync. These estimates are informational only and are not medical advice.
