Natural Cycles places birth control into your own hands.

Founded by particle physicist, Dr. Elina Berglund, with a goal to offer women an effective, hormone-free method of birth control, Natural Cycles identifies ovulation by analyzing basal body temperature, learning your unique cycle so you can get to know your body better, and know the exact days you can and can't get pregnant.

Natural Cycles is a clinically-proven birth control option alongside the pill, IUD and the condom. 93% effective with typical use, and 98% effective with perfect use. The clinical study that determined Natural Cycles' effectiveness is one of the largest of its kind, with 15,000 women and 600,000 menstrual cycles. It was peer reviewed and published in the renowned journal Contraception.*

The app supports syncing with Apple Health.

○ Yearly Plan (Recommended): $89.99/year.
○ Monthly Plan: $9.99/month.

Jeg og en venninne av meg ble begge gravide på denne appen. Vær så snill og ikke stol på denne appen om du ikke ønsker å bli gravid!

Super som prevensjon for 30 åring

Har brukt appen i snart 2 år. Fungerer veldig bra som prevensjon. Lærer utrolig mye om syklusen min og kroppen! Når jeg vil prøve å få barn vet jeg allerede eksakt når i løpet av syklusen jeg skal prøve. Veldig fornøyd! Kommer aldri til å begynne på hormonell prevensjon igjen!
