NaturalCycles is a fertility monitor that predicts and identifies your fertile window. We track your period, predict and find your ovulation day as well as your fertile days and provide you with a menstrual/fertility calendar.
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 you are fertile or not.
A green day is to 99.9% not fertile. During red days, you may be fertile.
You can optionally combine your temperature data with ovulation test results - NaturalCycles tells you when, for optimized usage. NaturalCycles has been scientifically tested and shown to be highly effective at determining and predicting ovulation day and hence the fertile window. With NaturalCycles there is no room for the human error. You measure, we analyze and you decide the rest!
If you want to get pregnant, we recommend you to use NaturalCycles Plan. NaturalCycles isolates your most fertile days in your cycle and detects ovulation. Once pregnant, NaturalCycles monitors your pregnancy and follows your baby’s development.
