I LOVE this app, clean username, many themes and animals to choose from for customization preferences, very easy to use and understand, I've tried many other period apps and found that tracker is hands down the best completely free period tracker in the market. I've used ir for YEARS never made a review but as I was in editing my cycle and was prompted to review and I said atp they deserve it, i cant gate-keep, I gotta say something so here i am saying what are you waiting for? GET IT!

fantastic little app. the free version, cuz I'm broke. very well-rounded lots of things to choose and symptoms, also a note section so you can leave your own little comments. I'm also on a mission to get all the pets and backgrounds, I will watch all the videos. :) it does send me alerts occasionally when I'm about to be on my period. I'll have to look and see if I can do it more often. I tend to forget things, always a surprise, monthly

Update! As of May 2024, you can now launch the app without having to watch an ad! Thank you so, so much! Very pleased! I used to rely on this app for all sorts of logging and biometric journaling. I even recommended it to my clients (women's health). But the ads keep getting worse and worse. I can't even open the app without a 15 second ad first. It's one thing to have them buried inside when accessing certain features, but requiring an ad to even open the app is frustrating & discourages use.
