Natural Cycles is certified for use as contraception and helps you keep track of your ovulation, period and fertility.
The app will show you when to use protection to effectively prevent a pregnancy. It is clinically tested to be 99.5% effective*.
*Natural Cycles has a method failure Pearl Index of 0.5, which means that 5 women out of 1000 get pregnant during one year due to a falsely attributed green day. Natural Cycles has a typical-use Pearl Index of 7.0, which means that in total 7 women out of 100 get pregnant during one year due to all possible reasons (e.g. having unprotected sex on red days, failure of the contraceptive method used on red days).
Natural Cycles analyses your temperature, period and ovulation to calculate when you are fertile and should use contraception (e.g. condoms). Our algorithm is the brains behind the app. It takes care of all the complex calculations and tells you everything you need to know about your cycle.
How it works:
Measure your temperature first thing in the morning before you get out of bed. You will need a two decimal basal thermometer to do so. Enter your measurement and other data such as period, sex and LH test results into the app.
Check your daily status. A green day means you are not fertile and cannot get pregnant. A red day means that you are likely to be fertile and should use protection.
Make sure to read the instructions of use before you get started. For the app to effectively work as a contraceptive, you and your partner should be comfortable with using protection such as condoms on red days.
Natural Cycles does not protect against sexually transmitted diseases (STDs).
Planning a pregnancy:
Natural Cycles goes way beyond contraception. With our ‘Plan a pregnancy’ mode you can get to know when you are most fertile and time your sex to increase your chances of conceiving.
The app will let you know when it’s best to take a pregnancy test. Once a positive test is entered into the app, it switches colours and your features change. You will now be able to track the development of your pregnancy. Once you’ve given birth you can easily switch to Natural Cycles ‘Prevent’ mode as a contraceptive.
