Want to prevent pregnancy without hormones? NaturalCycles is 99.9% safe and 100% natural. We track your period, find the ovulation day for you, predict your fertile days and provide you with a menstrual/fertility calendar. It's the perfect natural contraception!
NaturalCycles is the modern birth control method - 99.9% safe and 100% natural.
This is how it works: you wake up in the morning, measure your temperature in your mouth and enter it into this app. NaturalCycles will return you a red or a green day depending on whether there is a risk of pregnancy or not.
A green day is 99.9% safe. During red days, NaturalCycles recommends the use of condoms.
You can optionally combine your basal body temperature data (BBT) with ovulation test results (OPKs) - NaturalCycles tells you which days to take an ovulation test, for optimized usage. NaturalCycles has been scientifically tested and shown to be highly effective at determining and predicting ovulation and hence the fertile window. With NaturalCycles there is no room for the human error. You measure, we analyze and you enjoy hormone-free birth control!
You can also use NaturalCycles if you want to get pregnant. With NaturalCycles Plan, you can simply get pregnant when you want to - no more trying! NaturalCycles isolates your most fertile days in your cycle and detects ovulation. Once pregnant, NaturalCycles monitors your pregnancy and follows your baby’s development.
Choose in your profile settings NaturalCycles Prevent if you want to prevent pregnancies and NaturalCycles Plan if you want to plan a pregnancy and are trying to conceive (TTC).
