Focus on "the five W's" to uncover your app's tapworthy conditions.
Focus your app's features for away-from-the-desk contexts. Consider the mobile mindsets: microtasking, local, and bored.
Identify what makes your app different from similar apps. "Skills" and "charisma" set apps apart.

Think big, but build small. Give users just enough to do what they need.
When building a website companion app, consider how to improve on a mobile website, not just duplicate it.
