Frequently Asked Questions

Ovulation is when a mature egg is released from the ovary, typically around the midpoint of your cycle. The egg is viable for fertilization for roughly 24 hours afterward, which is why the days leading up to and including ovulation matter most for conception.

Tracking helps you identify your fertile window, spot patterns in symptoms and mood, and notice changes that might be worth discussing with a doctor — whether you're planning for pregnancy, avoiding it, or simply getting to know your body better.

Ovulation Tracker uses the cycle data you log — such as period start/end dates, symptoms, and optionally basal body temperature or cervical mucus changes — to estimate your ovulation window using established cycle-tracking methods.

Your fertile window is the five days leading up to ovulation plus the day of ovulation itself — the days when pregnancy is most likely to occur if you have unprotected intercourse.

Ovulation Tracker adapts its predictions as you log more cycles, so irregular cycles are supported. Predictions may take longer to stabilize and carry more uncertainty than for a very regular cycle, but the app will still surface the best estimate it can.

At minimum, logging your period start and end dates each cycle. The more consistently you log — including symptoms, temperature, or mood — the more personalized and accurate your predictions become over time.

Projections are statistical estimates based on your logged history, not guarantees. Accuracy generally improves the longer you use the app and the more consistent your logging is, but no cycle-tracking method can predict ovulation with 100% certainty.

No. Ovulation Tracker is an educational and informational tool only. It is not a certified medical device and is not regulated by the FDA or an equivalent body.

No. Ovulation Tracker should not be used as a form of contraception. Cycle predictions are estimates and are not reliable enough to prevent pregnancy on their own.

Yes — always. Ovulation Tracker can help you notice patterns worth discussing, but it does not replace professional medical advice, diagnosis, or treatment. Consult a healthcare provider for any health decisions or concerns.
