With My Mikvah Calendar, you can keep track of your menstrual periods in a way that is both easy to use and completely private. Simply enter the date and time of your last period, and My Mikvah Calendar will take care of the rest. The app will calculate your times of separation and send you reminders of these upcoming times. You can also learn how to do the calculations in a detailed way, so that you know exactly how to follow halacha (Jewish law). The app also includes a comprehensive halachic overview of the laws of family purity and a preparation checklist to help you get ready for mikvah night.
