Health Export Kit vs PRMaxxing

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.

I built this app because I wasn’t finding a logger that treated lifting like lifting. Most apps pushed gamification, AI coaching, and social features that got in the way. So I built the app I actually wanted in the gym. That means a completely free app for experienced and serious lifters. No social features, no gamification, no internet required for logging, and no AI. I didn’t want another app trying to motivate me or tell me how to lift. I wanted to build my routines the way I wanted, log sets easily with the features I wanted, and look back at honest training history. PRMaxxing is that. What you get with my app * Fast set logging built for the gym * Full routine control: set types, rest timers, supersets, unilateral logging and more * Honest history you can edit, with real PR tracking * Automatic progression schemes * Many graph types and tracking tools that show real progress * Warmup presets you can tune your way * Completely free, with no accounts, and no data tracking.
