Disclaimer: Period Tracker period and fertility forecasts may not be accurate and should not be used to prevent unwanted pregnancy. To forecast ovulation Period Tracker calculates 14 days before the projected start date of one's next period. Forecast accuracy depends on a number of factors including how regular one's cycle length is, when one actually ovulates during the cycle, and how many periods have been logged in the app. Anxiety, stress, diet, nutrition, exercise, environment, medications, age and other factors can also affect one's cycle from month to month.

🌍Geographic ReachNot ranked
This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.
