Ads ads everywhere and all this just to track my periods?! This is ridiculous. 2 stars because it USED to be a great app, but lost 3 simply because of the incredibly obnoxious ads. You guys need to realize you can still have ads on your product and it be OK - but as soon as a user can't click on something or even open the app at all without full page ads that's when it becomes unacceptable.

Hi Bethanie, sorry for the unpleasant experience! Could you send a video of the issue via "Settings -> Bug report & Feedback”? It will help us locate the problem and optimize it quickly. Our app is free, so we introduce these to ensure team operation. However, we will try to optimize its presentation to minimize the disruption. Thanks.🌹

I've been using this app for two years now. It's been great, no issues. I never started using it "fully" until a few days ago, where I actually plug in my water intake, symptoms, etc. Usually, I've just been noting when I start and end my period. Although, I haven't used the self care sections, it's been nice. The ads aren't troublesome at all for me.

I wanted a simple no-frills app to track my period and symptoms and this did exactly that. Predictions about your next cycle are pretty accurate if you're regular. Ads were unobtrusive and you can get rid of them entirely with a one time payment. And there's some customization so you don't have to see tracking about your fertility/pregnancy if you don't want to. Nothing fancy but it does exactly what I need it to
