This is the best app ever. Thank you for the cycle info and all this stuff but first of all thank you for the chats! They are the best and people are kind and supportive. It’s beautiful! The chats helped me to get out of a toxic relationship and helped me realised that my mom is toxic and I got so much comfort and support! Incredible! Thank you!

Flo keeps asking me for paying again and again and again after I already paid my one year and just don’t want it anymore. It keeps charging my card and I can’t change a thing about it. All the little sites are poorly programmed and the AI assistant doesn’t even remotely help. There is NO Flo subscription on my Apple device and whenever I go on the site to change it, it just makes me pay again. I like Flo but the system it has in place is just horrible and makes me want to uninstall it and tell everyone to stay away from it.

Delia00778
This is a very good app. But the problem is that it is not romanian language. So when I read some advice in russian or english, i don't understand so much. It would be very good if you were to update and to introduce romanian and other languages. Please, draw attention to this. Thank you !
Developer Response

Unfortunately, there is no such option at the moment, but we are constantly working on improving our app. Our team will definitely review your suggestion to determine if it's possible to implement and how to make Flo more useful to our users.Best Regards,Flo Support Team
