## Period & Fertility Tracker Description
Discover your body’s rhythm with an easy-to-use menstrual cycle and ovulation tracker.
Simply enter the first day of your last period, and the app estimates your next period, ovulation day, and fertile window.
With Apple Health sync, your data stays automatically updated across all your Apple devices — so your fertility insights are always with you.

* Two Calculation Methods *

Our app includes two baby gender prediction methods:
 • Popular Method – a theoretical approach based on the well-known theory by Landrum Shettles, which suggests that the timing within the fertile window may influence the baby’s gender.
 • Scientific Method – a statistical, research-based approach developed by Rodrigo Guerrero, grounded in large-scale data from thousands of women.

You can switch between them anytime in Settings.
Please note: both methods provide probabilistic insights, not guaranteed results.

* Full Version Features *

Unlock deeper insights with the full version:
 • Daily pregnancy probability for any selected date.
 • Gender prediction probabilities for each fertile day.
 • Overall fertility chances during your current cycle.
 • Automatic Apple Health sync between devices.

* How It Works *

To create your personal fertility calendar, simply provide:
 • The first day of your last period.
 • Your average cycle length.
 • Your luteal phase length (default works for most users).

Predictions work best with regular cycles and are estimates only — every body is different.

* Know Your Cycle *

Keep track of your periods, ovulation, and fertile window in one clear calendar — made even smarter with Apple Health integration.

### *---- "ขอวิธีการใช้หน่อยค่ะ"

-- Peemook, 2023-10-31

### ***** "It works!"
I used for both of my pregnancy. I got a boy and a girl as I expected! It took me couple months until I can track my period correctly. But once it’s correct it took me another 3 months until I got the first pregnant. It was a boy. And after I gave a birth, I start tracking since month 6th then I got a girl for our first try. :)
