Comments on Period Tracker and Calendar for Android
★★★★★theresa Hernandez· Aug 17, 2026
Love this app been using it for years!!!! I even used it during the pregnancy mode and everything, and it helped me stay on track with my pregnancy and after pregnancy and even to now I've been using it over 8 years
★★★★☆Michelle Collier· Sep 5, 2026
When I started using this app I learned why I couldn't keep track of my period. I cycle every 3 weeks not every 4 weeks. It has a lot of other neat features that I would have liked when I was young and looking to have babies. Now I'm using it to track my perimenopause, so I will know when I finally have been period free for a year, which as I understand it, is what they call menopause. I could be wrong on that too, live and learn! Cool app.

I love it it is so accurate, and it helps me keep track of my cycle I do recommend
★★☆☆☆Leslie Mahr· Aug 25, 2026
I have been using this for the past month, but I don't like that I can't change the ovulation date, and I can't really edit my symptoms or anything because I don't want to do a subscription. Yes, there should be like a premium for if you want extra things, but I would like to be able to track my symptoms and a couple other things associated with having a flow, so I can really keep track of my cycle. You shouldn't need a premium to do the basics.
