I have used this app since December 2015! It is that great. I can even track my daughter's period since she started a year ago. Now that I'm getting older I would like to track perimenopause. I looked around on the play store but I would really like to keep THIS app bc I like it so much. Maybe you could add that feature as well??

This app knows my period better than me. I have used it for 8 years now and it has helped so much. At one point I was having irregular periods and this tracker was able to help my doctor find a pattern(don't worry it's all good and regular again). It tracks symptoms, duration, flow, fertility, ovulation, water intake, etc. It helped me find a pattern so I know what's going to happen when(more than before I used this app). It also has customizable themes.

I absolutely love this app. It's helping track my moods, symptoms, and weight. It's very helpful, and it's overall really easy to use and super cute, too! Edit. I STILL love this app. I find it SUPER helpful. I love that you can track your weight, mood, ovulation, and other things. I also love that you can shut some features off, such as the ovulation and a few others. Great app and highly recommend
