There’s an App for That – Birth Control

FDA allows marketing of first direct-to-consumer app for contraceptive use to prevent pregnancy.  

The app, called Natural Cycles, contains an algorithm that calculates the days of the month a woman is likely to be fertile based on daily body temperature readings and menstrual cycle information, a method of contraception called fertility awareness. Designed for mobile devices, it is intended for use in pre-menopausal women aged 18 and older.
