Customer Reviews

So helpful

This app is amazing! I have used many other apps to track my cycle and was disappointed in a lot of them. Flo does much more than track my cycle. It tracks when I ovulate when I’m supposed to get my period. If I miss my period it tells you the likelihood it will come the next day. It uses the information you log on the app to improve their predictions. It also gives you heal insights and it really is a big community. I really enjoy reading and learning on this app and being able to know I’m not alone.

Great App!

Thanks to Flo, I have been able to keep better track not only of my periods but also my mood and the migraines I get frequently. The app features a simplistic design and a lot of flexibility as to what and how you track stuff in the app (for example, I’m not sexually active so I was able to turn off the sex-tracking function). Best of all, it’s 100% free! I love this app!

Avoid the comments

This app is really great and allows you to track your period and even gives you tips on dealing with them, but going to the comments from other users is not such a great idea. There mostly from 12-14 year olds who make up stories and don’t know what their talking about 😑
