What it does

Predictions you can plan around

Your next period and fertile window, computed from the cycles you log, with a give-or-take instead of false precision. Every period you log makes it sharper.

Trying, or expecting

A wider fertile window and conceive days when you are trying, and a pregnancy mode with week-by-week progress, a due date and checklists once you are.

Don't even open the app

Home Screen and Lock Screen widgets, a Control Center button to log a period, Live Activities on period days, and one calm notification at the time you choose.
