Modern, Research-Based Fertility Tracking

Using Cycles for family planning means taking advantage of new scientific research more accurate than the 'rhythm method' of yesteryear that has a real-world failure rate comparable to that of condoms.

Even so, Cycles is designed for informational purposes only and should not be used to prevent pregnancy.

    Never knew how easy it would be to keep track of my cycle. Wish this would have been around since I was 12.

    Excellent App

    It is very accurate, easy to handle. I have tried it for 5 years and I managed to get pregnant by looking at the days that marked ovulation I recommend it.
