'Natural Cycles' is a Swedish smartphone app that is changing the way women track their fertility. By using first-hand data and an advanced algorithm, the app shows women exactly which days they are most fertile.
Natural Cycles is a user-friendly smartphone app and thermometer that helps women track their ovulation and fertility. To use the system, a woman begins by taking her temperature first thing each morning and entering the corresponding data in to the app. Over time, the app uses the data collected to show the woman when she is the most fertile. The app is backed by clinical studies that show it can be extremely accurate, even for women with irregular periods or those with conditions such as Endometriosis and Polycystic Ovary Syndrome.
By combining real data about a woman's basal body temperature with an ovulation-tracking algorithm, Natural Cycles gives women a simple and accurate way to predict pregnancy.
