Best period app ever

It has so many functions and it’s free! I downloaded this expecting it to help me keep track of my period, it’s been off lately and I want to be more organized in keeping track. As I explored the app I realized it can also help you keep track of sleep, water consumption, weight, symptoms and a lot more! I have problems with heartburn, dehydration, sleeping and weight and this app is perfect for me! Best part is, its all free! (From What ive seen, Ive had it for a week). It also lets you write in a “diary” where you can kept track of other stuff such as exercise and what food you eat. It also includes free stretches to help aid with cramps and to strengthen muscles. It also tells you what your chance of getting pregnant is (I don’t need this right now, but I will in the future!) There are some ads, more than I’d like, but I love the free features so much I won’t complain about the ads. This app is perfect. It won’t waste your time or your money

The best app, period!

This app has so much to offer. I have downloaded pretty much every period app there is to offer for free. Then I came across P.C a few months back. I use this app daily because it has so much more to offer than simply being a period tracker. With this last update I got this morning you guys have really impressed me. I went to enter my weight and seen the new set-up. My favorite part of the update is what you did with the “reports” menu. It’s so easy to navigate through the app now. The new front screen is great as well. I appreciate the fact that I can’t watch an add to get a pet instead of having to spend money. The reports area being updated was just a really great surprise. Lol Thank you for making such a great app. I also want to give thanks to all the people who help make it into the awesome app it is. 🤗

I liked this app until I got pregnant, updated

I would have given this app five stars, right up until I found out I was pregnant and tried to turn on the pregnancy function. Despite knowing exactly how far along I am and my due date, the app will not allow you to change the date of conception. It just says 5w3d no matter what I do. There is no further options in the weeks beyond 5. I’m currently 9w4d, so basically the app is now useless for me unfortunately. I know pregnancy isn’t the primary purpose of this app, but it is an aspect of a woman’s reproductive health and I would hope it to be at least editable as a feature in this app.
As per the developer’s suggestion, I tried to edit the date of my last period- I had to calculate the discrepancy in the app between how far it thought I was, and how far along I am, dragging the date of my last period back that much. My findings are a) it changed nothing and the app still calculated me as 5w6d, with no further options past 5 weeks.
b) it backed my last period prior to pregnancy up to the week after my period previous to that- so it looked like I had a period, had a week off, and then another period. And STILL didn’t change the date it calculated for me AT ALL.
c) the date of my last period is not the problem. That is the same date I gave to my two other pregnancy apps AND my doctor, and they all told me the same accurate date/ length of pregnancy so far.
P.C.’s algorithm is the problem.

Developer Response ,


Thanks for your feedback.

You could try to delete or edit the start date of the last period. In our app, the estimated start of gestation is calculated as the first day of your last period.

We are working on this function and will improve its calculation for a better user experience. Thanks so much for your feedback.

If have any other problem, please feel free to contact us

Best regards,
