What is a menstrual cycle calendar tool?

A menstrual cycle calendar tool is a digital resource that overlays your cycle phases onto a calendar you already use, like Google Calendar or Apple Calendar, so you can plan your work, rest, and daily life with your own pattern in mind. Rather than just tracking when your period is due, it shows you all four phases: menstrual, follicular, ovulatory, and luteal.

Is Nadi an app I need to download?

No. Nadi's menstrual cycle calendar tool overlays onto the calendar you already use, Google Calendar or Apple Calendar. There is nothing new to download. Nadi's education, support, and community are delivered through newsletters and events.

How is Nadi different from period tracking apps like Flo or Clue?

Period tracking apps typically focus on predicting when your next period will arrive. Nadi is designed for planning and awareness across all four cycle phases, focusing on understanding what each phase means for your energy, focus, mood, and capacity. Nadi also integrates directly with the calendar you already use, rather than requiring a separate app.

Does Nadi work with a smartwatch?

Yes. Because Nadi writes your four cycle phases into Google or Apple Calendar, any smartwatch that displays your calendar shows your phases on your wrist automatically. This includes Apple Watch, Pixel Watch, Galaxy Watch, and Garmin or Fitbit that show your calendar.

What is Nadi, if not a phase-rules system?

Nadi is menstrual cycle awareness. You notice your own pattern of energy, mood, focus and pain, and map estimated phases into the calendar you already use. It is not a set of universal rules that say follicular means X for everyone.
