Keep Your App Simple
Your app should be so intuitive that it can be learned in a matter of seconds. If you’ve created a game, I should be able to learn how to play the game within seconds. Or I should at least be able to understand the premise of the game in less than a minute. Sorry, but we don’t have big attention spans and we want to play a game quickly and easily. Some apps have a little tutorial to explain its use. But the draw of the app has to be so strong that someone is willing to invest a little time to read the tutorial.
