## Description

Track ovulation, fertile days, and pregnancy chances with a science-based fertility calendar. Enter the first day of your last period and your average cycle length to receive predictions for your next period, ovulation day, and the most fertile and least fertile days. Apple Health sync keeps your fertility insights up to date across devices.

Choose between two baby gender prediction methods: Popular Method (based on Landrum Shettles) and Scientific Method (statistical approach by Rodrigo Guerrero), switching anytime in Settings. The full version adds daily pregnancy probability, gender probabilities for each fertile day, overall fertility for your current cycle, and cross-device Apple Health sync. Note: these methods provide probabilistic insights, not guarantees, and this app is for informational purposes and does not replace medical advice.

## Review summary

Users largely praise the app for its ease of use and strong cycle/ovulation tracking, which many cite as helping them conceive or plan pregnancies. The gender-prediction feature (with two modes) is a notable recurring topic, though its accuracy is contested. Common drawbacks center on confusion between prediction modes and questions about the reliability and value of the predictions. Overall, used with realistic expectations, the app is considered a helpful, time-saving fertility tracker.

### Pros

- Comprehensive cycle/ovulation tracking (and intimacy tracking) that helps with planning and managing fertility

### Cons

- Gender predictions are not scientifically reliable and can be misleading
- Two modes (popular vs scientific) can cause confusion about which to trust and lead to inconsistent results
- Predictions and outcomes are not guaranteed and accuracy can vary between cycles
