Tips
  • With flow tracking on, tap a logged day to cycle light → medium → heavy → unlog. Older logged days without flow data show as medium.
  • Long-press (or right-click) a logged period day to exclude that whole period from averages and predictions.
  • Tap the Calendar icon again to jump back to today.
  • Periods with up to 3 gap days still count as one period.
  • Muted colored tiles are predictions.
