1. Write 2-3 sentences about each potential user type for your app. 2. Assume each of the users will spend a max 1-3 minutes on your app, do just 1-3 actions. Which would these minutes be spent on, what are those key actions? 3. Find some white paper and a thick calligraphy pen. Draw the flow in very broad outlines, as a storyboard. Max 3-4 screens per flow. Paper and pen are the best. Forget computers. Forget details. 4. Think if those key flows are something users are willing to pay money for. If not, start over from 1. 5. Once you have a few short flows where users would go mad and pour money over you, start thinking about wireframes and details of the mockups.
