Super great definently helps with my periods. Yes, the pop-ups can be quite annoying. You can't understand your body better without paying money, but my favorite feature is the secret chats! It's very nice to be able to share your experiences with other people, especially doing it anonymously bc you can get down to the nitty gritty about everything! Really like this app more than the other ones.

At first it was helpful and accurate, I used it for a year or two without issues. Recently it's stopped responding/updating the cycles. So I literally ended a cycle and it's telling me I should be more than halfway through the cycle. I've input days, and it's not updating the pattern. It's on a set calendar and doesn't waiver no matter what data I put in..which is unhelpful

Long time user of the app. Some wishes, like a single buy system instead of a subscription system. It harasses you to subscribe with the discount price that never changes. I miss the old days when I could learn something from the app without it harassing me with a paywall. The only reason I still use it is because of the accuracy but it's oddly not as good as it used to be. Recent news articles has me not feeling safe to use the app. Privacy and selling data issues.
