The First FDA Cleared & Only CE Marked Birth Control App

  1. Read Your Daily Fertility Status
    After adding your temperature, you will get your fertility status for the day. This is either green (not fertile) or red (use protection). If trying to prevent pregnancy, you should use condoms or abstain from sex on red days.
  2. Track PMS Pain & More
    Add optional data throughout your cycle including changes to mood, sex drive, PMS and pain. Tracking symptoms can help you learn even more about your unique menstrual cycle.
  3. Understand Your Cycle
    Our popular graph feature helps you identify patterns in your cycle. You can also view the symptoms you have logged. Easily compare cycles or zoom out for an overview.
  4. Adapt Your Fertility Journey
    Natural Cycles is a long-term fertility partner. Switch between NC° Birth Control, NC° Plan Pregnancy and NC° Follow Pregnancy depending on your journey.
You must be over the age of 18. Does not protect against STIs. No method of contraception is 100% effective.
