What it does:

* Reads sleep, HRV, activity, body oxygen (SpO₂) and skin temperature from Health Connect
* Computes a 0–100 readiness score calibrated to your own baseline
* Explains the number in plain English, written on-device by Gemini Nano (rule-based fallback on other phones — same score)
* Live status-bar score on Android 16; honest, partial-aware scoring when a signal is missing
* On-device only — no account, nothing uploaded
* Free to download, one-time $4.99 Pro (no subscription)

Android 9+, US + Canada at launch. Solo dev — happy to answer anything.
