The Natural Cycles app has become an invaluable tool that allows women to know everything about their body’s fertility, empowering them to make informed decisions.

The first FDA-cleared app of its kind, Natural Cycles is a 100% hormone-free birth control method that’s 98% effective when used perfectly -- and 93% effective when used typically, on par with other methods like the pill or vaginal rings. Simply check your temperature when you wake up each morning and enter or sync the reading into the Natural Cycles app.

The app can pinpoint your daily fertility status using an algorithm along with other fertility indicators. If you aren’t fertile, the app shows green. If you are, it’s red. So whether you’re trying to avoid pregnancy or if you want to start a family, Natural Cycles presents that vital information immediately.

Over time, Natural Cycles becomes even smarter, learning the patterns of your cycle to give you the insights you need to get on top of your fertility.

New users can get 20% off their annual Natural Cycles subscription and a free basal thermometer using the code NC20.
