I got Flo when I was a teenager, now I’m a full adult and I’ve consistently used Flo to track my period and it’s really synced with my body and gives me the most accurate information about my cycle. I have been able to live around my cycle knowing my wins and struggles, what’s normal and when I have to be concerned and why I feel the way I feel, it has truly made me better understand my body and femininity and I really credit Flo for helping me get here. I can’t recommend it enough to all the women around me.

Can you please add a feature where we can use a picture from our gallery for our profile pictures? You can tell other people’s interests when you see their profile and makes the secret chats more fun! Can you also not make it apart of the premium? Not everyone can pay for it, since most people on Flo are teenagers. There are a lot of other features that can makepeople pay for premium. I hope you can consider this suggestion, please reply with your answer as soon as you can. Flo is one of the best period tracking apps i’ve come across and adding this feature will make it an even better experience! Thank you.

Great app to follow your cycle and also understand why sometimes women have mood swings or headaches or etc. I like that it has a lot of info for better understanding of oneself. It’s super educating and I wish I had it when I was teenager.

Super annoying
meemanonymous
I’ve been using this app for years but it keeps becoming more annoying with every update. Too many pop-ups desperately trying to make you subscribe that it just makes you want to close the app as soon as you open it. I just want to track my cycle, I don’t need all of the useless extra stuff on the app, and it makes having a free plan an unbearable experience. The app is just not as convenient as it used to be.
Developer Response
