Emuqu

Problem

Consumer recovery apps reduce physiology to a generic score. They lack signal quality controls, ignore personal baseline context, and give no access to the raw session data needed for serious self-experimentation. If you want to know whether your body actually recovered overnight, you’re stuck trusting a black box.

What Shipped

It connects to a Polar H10 chest strap or Verity Sense armband via Bluetooth, records heart rate variability during sleep, and produces a recovery assessment using DFA α1, ln(RMSSD), and time-domain metrics scored against a 60-day rolling personal baseline.

The app uses a dual-architecture recording system — one path for overnight sessions, one for on-demand spot checks. Sleep staging runs a six-component analysis. PDF reports are generated on-device.

Beyond sleep, Emuqu tracks workouts and training load across ten sports — Polar straps, Apple Watch, Stryd foot pods, FTMS trainers, and the Concept2 PM5 — with GPS routes, live DFA α1, and an offline compass that points straight back to the start. A built-in assistant answers questions from a typed catalogue of your own measurements, running on-device through Apple Intelligence or your own API key for Claude, ChatGPT, Gemini, Grok, or DeepSeek. It will not diagnose, prescribe, or discuss your heart rhythm.

No wearable’s composite recovery score has been validated against outcomes, and the app says so: scoring is versioned, every heuristic is listed with its evidence status, and a copy linter keeps medical claims out of the interface. Every line of Swift was directed by AI — 220,000 lines in Swift 6 strict-concurrency mode, with 3,000+ unit tests and 46 scripted CI gates, and no force-unwraps, TODOs, or fatal errors.
