01Rate one thing. Each morning: your calm, 1–10. Five seconds. Subjective on purpose — it's your outcome, not a wearable's.

02Context rides along. Sleep duration and screen time from Apple Health / Health Connect add context if you connect them. Optional, never required.

03A verdict that admits uncertainty. Likely helped · no clear difference · likely made it worse — with how confident, not just which. Too few clean days? The app says so instead of rounding up.
