overall very accurate. whether it be predicting how I'm going to feel or other things like that, it's very helpful. one thing I don't like is how you have to pay for half of the features. don't get me wrong, if a had the money I 100% would buy premium because it is definitely worth it, but I don't have the money so unfortunately I cant. Great app though, would recommend as a period tracked!

The app is good for tracking things, but I don't think I'm going to use it anymore. I wanted to start the free trial and it ended up making me choose a subscription (which I've since cancelled). I only wanted the free trial to check one post, but now I'm £28.99 down the drain for something I don't plan on using long term. It's just my mistake, but it has left a bad taste in my mouth :(

I've used this app for many years and love the prediction and analysis data and anonymous features. The bad is that while I understand the purpose of premium, I feel like it gets push way too frequently and caused me to use the app less (only for tracking). When they introduced the partner feature, it was so limited that my partner paid for the premium which then gave it to me. The partner feature is great but needs some work which I'll submit through their email.
