This app has been very helpful! It has many many many options, has no adds, and has plenty of privacy. It is free and is the best period calendar I have ever gotten. You can always delete data, which I find very helpful. It also helps tell you how you can get rid of cramp pain and helps you with mood swings, really any pain, emotions, support, ect. I deeply think that you should get this app, it is very helpful. And if you don't like something on it you can always change it or contact them.

Best app, doesn't require anything from you to use it. Cute themes, simple and easy to use. On the symptoms part, I wish we had more of a variety to log such as "lack of appetite" or things to add custom. I'm sharing my well-being with my partner and it would also be nice to have more options for him to see on the 'moments' section. I also can't find an answer to my question I had about what he sees. I know I can choose to let him see a few things, but what about if I log any notes?

I've been using the app for a few months now. I have learned a LOT about my cycle using this app. For example, I prefer to skip breakfast but there are parts of my cycle when I get really tired when I do this (usually right before my period starts). This app makes it easier to predict when I should have a good breakfast and when I can skip breakfast to fast longer. Tracking is simple and easy and the predictions are very helpful!
