Period Tracker / Calendar - For Android

- First off thank you for designing an app that doesn't look like it was made for and by a 12 yr old girl, it's so frustrating that almost all the period/ ovulation tracking apps on the market are bright pink and covered in flowers. I love the simplicity of the design and the cycle wheel and colour coding as a home page are a welcome change from the normal cluttered calender view (although I am happy there is the option to view the calender for a more detailed analysis).
