Modern, Research-Based Fertility Tracking

Using Cycles for family planning means taking advantage of new scientific research that’s more accurate than the rhythm calendar method.

Even with a real-world failure rate comparable to condoms, Cycles is designed for information only and should not be used to prevent pregnancy.

Gcamden
Cycles has helped me track my irregular period and find the pattern and better my understanding of my cycle.
Great app
Corrie153
We also used this app to get pregnant and our little one was conceived on our very first attempt due to ‘getting active’ on the day it stated I would be ovulating.
Great app for tracking

I love this app, let's me log my temp, how I'm feeling physically and emotionally, and obviously when I'm ovulating and my period.
