It used to be Awesome. It does still calculate my cycles nicely. And its not just a tracking app, but also gave brilliant details, tips and facts about the female body. BUT, after using it for 5 years.. recently Ive discovered that all of those basic tips and info and even the secret chat has been removed from Flo, which really sucks. I understand you should pay for more info, but its a bummer that they reduced the value for free users.
