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.

This app works extremely well. It has cute graphics and a calming look. The predictions for my next period are very accurate. It also counts day apart from periods for you which is nice. It has a great mood chart too and notes sections so you can keep track. It also has a password and you can also use fingerprints. Oh you also can get notifications letting you know your predicted to have your period soon. It is really nice, thanks for reading. Hope you have a good rest of your day!

It works ok. The intrusive ads are annoying, but my biggest gripe is the way the app treats pregnancies. You toggle "pregnancy mode" on and off, which means that 40 weeks of pregnancy (plus however long it took you PP for you to get your first period) is considered one long cycle and counted in the average. As a result, my "average cycle" is 75 days, which makes it useless for predicting my next period.

Hi, usually, if pregnancy mode is enabled during pregnancy and turned off promptly after delivery, it won't affect cycle length or future predictions. If the issue persists, please contact us via "Settings -> Bug report & Feedback" for more help. We will also continue balancing user experience with team operations. Thanks for your support.
