Haoya Period Tracker &Cycle

Haoya Period Tracker & Calendar is a cross-device menstrual tracking app for iPhone, iPad, and Mac. It can sync data from Apple Health, support partner accounts with customizable permissions, and forecast ovulation and fertile days to help plan pregnancy or contraception. The app also offers widgets, multiple color themes, and extensive data recording options including flow, mood, symptoms, basal body temperature, cervical mucus quality, ovulation tests, weight, medications, and notes.

It includes autonomous analysis that adjusts forecasts based on your BBT and ovulation data, and tools to exclude abnormal data by analyzing the last 12 months. Users can manually include or exclude data, customize what is shown, and reorder displays. Features like a basal body temperature chart, yearly and monthly calendar views with conditional data filters, conception probability trend, and counting mode enhance planning.
