HealthCare App (Android Material Design)

This is my first Material Design work for mobile health tech company and doctors. This app looks very simple and easy but it will help the doctors to calculate their patient's rate of deaths and make a surgical operation proceed smoothly. Available for some big hospitals April 2015 in Japan.
I hope this app will help a lot of doctors and patients in Japan as same as I was saved my life from some doctor when I was young.
This is just a little image of wireframe. I will put more work details and big images here soon.

Thanks
