I love flo so much. It's been the only tracker to adapt to an irregular period cycle right away, which has been such a big help to me. I love all the chats with others going through similar things and I love that I'm able to share it all with my boyfriend on his phone. it makes our lives easier. however, I really wish it had a way to track how different birth controls are affecting you and track insertion dates for non pill options, and maybe a reminder when to book that Dr visit.

Worst period tracker I ever used. Everything is about "conceive/pregnancy", like if women are nothing but reproductive machines. No thanks, child-free here and will keep this way. And as this wasn't enough, there's "sex" talks and mentions everywhere, and the option to turn off this whole topic doesn't even work. For me, this app was triggering, literally. Deleted.

I've used this app for many years and love the prediction and analysis data and anonymous features. The bad is that while I understand the purpose of premium, I feel like it gets push way too frequently and caused me to use the app less (only for tracking). When they introduced the partner feature, it was so limited that my partner paid for the premium which then gave it to me. The partner feature is great but needs some work which I'll submit through their email.
