## Fertility & Period Tracker Description
Discover your body’s rhythm with a scientifically based fertility tracker designed to help you plan or avoid pregnancy naturally.
Simply enter the first day of your last period, and the app predicts your next period, ovulation day, and the most fertile and least fertile days of your cycle.
With Apple Health sync, your data stays automatically updated across all your Apple devices — so your fertility insights are always with you.

* Scientifically Backed 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).

Ideal for women with regular cycles — but also reliable for estimating ovulation using your average cycle length.

* Empower Your Reproductive Journey *

Whether you’re trying to conceive or prefer natural birth control, this app provides clarity, accuracy, and peace of mind — backed by science and made even smarter with Apple Health integration.

## Fertility & Period Tracker Reviews in United States

### ***** "This app was spot on"
Used it to get pregnant 3 times
-- Gamerbaddie, 2025-07-24

### ***** "So helpful!"
My husband and I got pregnant the first month trying while using this app. Highly recommend!!
-- mckaelamlee, 2024-06-02

### ***** "Worked especially trying on the date of my highest fertility rate"
Keep tracking your menstrual cycles while on a healthy, nutritional daily plan so it can help your body to work with this. 
In the app aim for the date where it shows the highest rate of chance of pregnancy. 
I also purchased online the Premama Wellness Cleanser to detox my body from anything that built over the years along with purchasing the Premama Fertility vitamins, and I always took a really good quality Prenatal vitamin daily. I like the garden of life vitamin, so I continued adding that to my nightly supplements before bedtime especially because it had the proper vitamin D which my doctor said is needed for my body.
-- beautybotique, 2021-04-26

### ***** "Embra✌️"

-- CanadaON23!, 2019-10-25

### ***** "Accurate asf"

-- Jaii💕, 2019-09-09

### ***** "This app is dead on"
The last two times I was pregnant, the app was accurate on my conception date and also was accurate about the gender. I love this app. Since I don’t want to get pregnant, it shows me the days to be careful.
-- meaguilar07, 2019-08-24

### ***** "Love this app"
I have tried so many prediction apps but this one is by far my favorite. It’s easy to understand and it’s spot on every month. I even got pregnant and it was a girl day that day and 9 months later we had a baby girl. Love the app
-- mhk&d18, 2018-12-02

### ****- "Great app!"
Late update. I got pregnant and had a girl. Going to use this again and see if it works. Took me about 3 months the first time around.
-- Shundreca, 2018-01-06

### *---- "Learn some science"
Gender of a baby is determined by the sperm, not the egg. This app is duping you.
-- <3cutecat12<3, 2017-10-11

### ****- "Alriydh"
Good
-- Meshoo104, 2017-04-21

### ****- "Easy to use"
Simple and easy to use
-- Lizzy Ever, 2017-04-17

### *---- "Uhh"
I tried to add information and instead I was made to pay for the full version.

ETA-
So three years later I was told I could get a refund. I never paid for anything, I simply thought it was odd that I couldn't use the app at all without paying for it. It should be a paid download if that's what the developers want.

Ps- Don't appreciate my name being put as "not appreciative".
-- Not appreciative, 2017-04-14
