I've had this app for years and it used to be the absolute best! But the ads and pop-ups for the premium are constant and now I can't access even the most basic information for free. For example, it used to just show some expected symptoms for where I'm at in my cycle, now they're all blurred out. Also, a lot of the article that are in full view (but I wish were blurred out) are "How to get the most out of your orgasms" in all caps with two naked girls hugging each other. Will be deleting.

I absolutely love the app! Best period tracker I've used so far. But, I'm a busy college athlete, so some sort of "track cycle" notification would be awesome! The pop-ups are quite annoying too, but that's something I can work around. I hope you guys bring back the old themes soon. All the darker colored ones I used are gone, and the ones available now are too bright for me to use (I have sensitive eyes). Please bring back the old app themes!

Hi there! We really appreciate your feedback! We decided to temporarily remove the dark themes, as we're planning to make them even better and return the themes in the first half of 2023. Stay with us for the updates! Yours, Flo

I really enjoy the app for the most part. But this is my third pregnancy this year (first two ended unexpectedly) and instead of changing some of the information to fit me, it's very generic to a first time mom. Which is great, but I would like it more catered to me. Ive read the articles before and would like different information. Finding recipes or certain articles isn't easy. The search uses one word and brings up other things I'm not looking for.
