Basic and it works


I have been using this app for years now. It’s free which is great! I originally got this app so I could track my periods when I was planning on going out of town. I would know when to plan events or if I needed to bring tampons or pads. Yes I could update to a newer app but I feel like this app works for me. I am able to leave notes, mark when my period starts and ends. It even will show you a preview of next months period and when you may start based off your previous periods. You can mark when you’ve had protected or unprotected sex, if your pregnant, your pregnancy test was positive or negative, got on birth control, etc. You are able to back up your app as well. The only thing that I could say needs some work on the app is how you have to click a few times to select the day so you can mark if you’ve started your period or want to leave a note. This is the only annoying feature about this app. It would be nice to see the app add some new features like when you visited the doctor for a check up, if you took a plan B pill, added other forms of birth control on their like IUD’s. That would be great. Other then that, I like basic and clear so I’m sticking with this app.

This app is a must!


This app is definitely a must have. The accuracy of this app is what keeps me using it. I’ve had this app for years & it helps me keep track of exactly when I’m going to be getting my period every time. Sometimes it may be a day or two early but i still know because of this app when i should be expecting to get my period. Even the days that I’m ovulating it all calculates up to be exactly when the app says. I love it ! & i always tell my friends about it. Especially those who are trying to convince.

Predicts it to the date!


I don’t know how long I’ve had this app now but it’s been years now. It has some crashing bugs still but does not bother me because it’s not frequent that they happen. I only use it to track my period and this thing literally tracks it to the exact date I start. Which is great when I need to schedule waxing appointments and provide doctors with my last cycle information. 10/10 would recommend!
