Hey Siri, can I get pregnant?

While we’re not quite to the level of checking with Siri on fertility, if you’re curious what your daily likelihood of pregnancy is—you guessed it—there’s an app for that. Natural Cycles, an app that’s recently been certified as a method of birth control by the EU, tracks daily fertility using a highly accurate thermometer to register body temperature combined with details on menstruation to suggest chance of pregnancy on any given day. The app is the first of its kind to receive approval from a European health agency as a legitimate contraceptive and is an updated version of tracking fertility through a calendar. While conventional birth control is still more effective, the app does offer a natural alternative to better plan for or avoid pregnancy.
