Your Natural Cycles journey
What to expect
From the first day you add data, our algorithm will provide you with your fertility status. For most users, ovulation is identified during the first cycle.
Master your routine
The more data you add, the more our algorithm learns. Measure your temperature when you wake up, at least 5 days a week, to get more green days (aka non-fertile days when you don’t have to use protection).
Keep on Learning
Track your period, ovulation test results, and PMS symptoms to help you learn more about your body, cycle, and reproductive health.
