Menstrual cycle
From the app’s English Help & Guide · Reference release 1.0.19
Overview
If Periods is enabled in Preferences, Metered reads your cycle phase from Apple Health, or from shared data if you use Tended or Steadied and haven’t granted HealthKit access. Menstrual phase: −1.5 spoons. Luteal phase: −1 spoon. Follicular phase: +0.5 spoons (energy rising). Ovulatory phase: +1 spoon (peak energy). Your cycle data stays on your device — we can’t access it.
