★★★★ "Unable to mark period ended. Have used this app a long time. Recently it has stopped allowing me to mark periods as ended. Why? This makes it useless to keep. I’ll have to find a different app." - StarsSoManyStars

Unable to mark period ended
Have used this app a long time. Recently it has stopped allowing me to mark periods as ended. Why? This makes it useless to keep. I’ll have to find a different app.

Privacy sucks!
They use a lot of trackers. What do they do with this information? I just looked at my app privacy report through the iPhone settings and saw this app was the one most violating my privacy, contacting 59 trackers in the last 7 days! Absolutely not! I won't allow this company to further use my information as if I'm a cash cow freely giving up my PRIVATE health information. Do they turn around and share your info to insurance companies? Pharmaceutical companies? To be deleted.

You should be ashamed
This is supposed to be an app designed to help women monitor a basic bodily function. Instead you: 1. Advertise incessantly and inescapably 2. Constantly ask if I want premium (for what!??) and 3. Claim you don't sell personal data (pii) but you DO sell analytics data, which includes app events, which includes every click in a session; given tracking a period requires a click, you ARE, in fact, selling cycle data to Google and partners. Monetizing off of women's bodies when all they want is to track their cycle. You're despicable.

Wouldn’t recommend for people with anxiety about tracking their period!
The app is now telling me that I’m 3 days late, which doesn’t make sense, as I am with another woman. It was great the first few months of having it but now it’s just filled with ads and misinformation. If you have worries or anxiety about your periods, this app is not good for you. Please make sure to get another app if you want to be more certain about your cycle!
