Great for the first version
Fabulous start -- even though functionality is limited. There are features I definitely wont use (like community interaction) and features that are missing (I already know Ruby is wrong in predicting my next cycle - how do I fix it? How do I edit/remove diary options? What if I want to log other moods?)
The part which I really liked - creative notifications to check out the app :)
