## Period Tracker and Calendar Reviews in United States

### ***** "Perfect!!"
I love my period calendar. It’s always accurate with my periods and ovulation. I’ve been using this app since 2014 and I love it!
-- draguOi, 2025-01-01

### ***** "Helpful"
It's awesome ✨
-- Youtab2003, 2025-01-01

### ***** "Nice"
It's a good app if your trying to keep track of when your period goes off and on.
-- Yfxdgh, 2024-12-31

### ***** "Amazing"
This app is amazing for when your on your period and you need a tracker. It’s for all ages and it’s AMAZING!!!!!
-- Mal!!!!!!!!!!!!!@, 2024-12-31

### ***** "Great"
Great
-- RaiCash, 2024-12-31

### ***** "Útil y práctico"
Tengo tantas cosas en la cabeza que me ayuda a recordarme los días previos al periodo y sus síntomas
-- Camiludezu, 2024-12-30

### ***** "Surprisingly Helpful for a Forgetful Person Like Me"
I have ADHD, and I have developed all sorts of tricks to help me remember things (I actually do tie a string on my finger sometimes). I found that once I started tracking my moods and symptoms along with my cycle I was able to notice patterns and then make changes to improve my day to day life. I’m not trying to have a baby, but I assume that this app would be helpful for that as well.
-- NixxieKnox, 2024-12-28

### ****- "Name change 👎🏼"
App is great. Lost a star from me because they changed the app name from “my calendar” to “my period calendar” so it’s obvious in my phone. My calendar was more subtle and I appreciated it being subtle. 
Works well otherwise.
-- Girlwiththoughts444, 2024-12-28

### ***** "AMAZING"
This app is so underrated I love this app so much
-- Ibuki.Mioda, 2024-12-27
