I'm creating my first Android application at work that shows state health rankings. It's very similar to this website: http://www.countyhealthrankings.org/. I have almost finished it, but I'm having trouble designing the home page layout. Right now, I just have our logo as an imagebutton and a textview that says, "How healthy is your state?" It looks pretty bad.
So my question is:
Is there some criteria for creating a good 'home screen' for apps? What should be included, and what should be left out? I'm asking this as a general question, but it would also help to hear suggestions that are specific to this health app.
The goal is to have the home page portray what the app is about, how it's helpful, and why users should use it.
