Ratings and Reviews
Definitely the best period tracker app
Firstly it has the nicest interface that is so easy and intuitive - it’s like using your iPhone. You can customize all the settings and notifications that are most useful for you and turn off those you don’t currently need. Secondly it calculates the most precise period dates for me so far which is a very important thing! I tried multiple period apps that are a bit overwhelming and less accurate. Love this one and would be recommending to my friends!
Very Simple and Easy
I am running this on iOS 14.0.1. This app is very simple and easy to use. It’s not cluttered with intrusive articles or other unnecessary features, such as forums, recipes, etc. You can customize not only categories, but the kind of cervical mucus, flow, mood, and symptoms you want to track. I can finally just check a box for the different types of discharge I have instead of writing it in a note. This app seems pretty new, but I hope it stays. I would even pay to help support the developers (nothing comes for free). The only reason I give it four stars is because of one crash, but again, the app seems new.
Love this app
I’ve only had this app a few days and I already recommend it to my friends. Love how you can track your entire life and even create new categories! Helps me remember the exact dates of my period and allows me to enter details that I can share with a doctor. I’m such an iffy person about period tracker apps but this was exactly what I was looking for.
