Comments on Flo Ovulation & Period Tracker for Android

★★★★★ Beryl Ann · Aug 15, 2026
I love it thank you for being with me in this journey
★★★★☆ Racheal · Aug 6, 2026
It's a great app that really helps you know so much more about your periods and more
★★★★★ Eliora · Jul 29, 2026
I've been using Flo for a few years now. It can be helpful with the predictions of when my period is due to arrive, but I have PCOS so my cycle isn't always timely. What Flo has done is encourage me to look at, and track, the symptoms around my period more, so I can tune into my body more and predict it myself in that manner.
★☆☆☆☆ Eva-May McAuley · Aug 10, 2026
Ah, yes. It's perfectly reasonable to make this app 16+ as if we all start our periods over 16. Let's also add constant "join our premium" adds and give us a SLIVER of the app, so we HAVE to pay. We totally didn't get our periods at 10 - 12, no bc that would be too young, and you're not allowed to be able to know about your menstrual health until 16. Great app. How stupid.
★☆☆☆☆ Daphnie Ozioma · Aug 14, 2026
This app has the worst onboarding experience ever. I downloaded on a new device, and I had to skip multiple questions and press next at least 10 Times to get to a screen that would enable me login. Why not ask if I have an account on the first or second screen before flooding an existing user with baseline questions. 2020 review: This is the third but most accurate period tracker I have ever used.
★☆☆☆☆ Taylor Breckenridge · Jul 29, 2026
Way too many requests to get me to sign up for the paid version. I could hardly navigate anywhere in the app without the pop-up blocking my screen. At least let me use it a little bit first. A period app more desperate than a man 🙄
★☆☆☆☆ Ovidiu Onica · Aug 2, 2026
Worst one I could get - you HAVE to be born 2009 or under like not everyone is born in the late 2000s or under. And plus - it's not really helpful for me, i don't like it
