Downloaded the app, only to be asked 3 million questions (some that had nothing to do with tracking ovulation), and then had to press some button on the screen for several seconds to "commit" to the app (super corny and annoying), only to then be told I had to pay yearly or monthly. The process is very tedious and frustrating. It doesn't matter what you click on on the app, if you haven't paid, you can't read anything. Frustrating and annoying experience. Uninstalling.

One of the best period tracking apps. I have been using it for over a year or two and the predictions are so accurate, it's so helpful to know exactly what's going on with your body! The flo assistant insights are really helpful as well, the secret chat is a great feature too! Girl to girl conversations without the fear of judgement are so refreshing.

Incredibly useful for tracking periods, as it adjusts to changes. I wish we could turn off, or skip parts of, the bot chat stuff. Its programming/information is too general and ultimately restrictive. I also would like more symptom options, even just an add your own that you can select again as needed. Thanks for the app!
