This app is super useful for tracking periods, and has given me mostly accurate predictions so far! I especially love that you can comment anonymously on posts and get help from and give help to the community.
Such an intuitive app! Hannah Malone

I've tried several period tracker apps on the market and nothing is as good as Flo. It's accurate, detailed providing you with an abundance of parameters to log, and they even provide useful articles and surveys to help you better understand the complex nature of the female body.
