Platform Friendly - Your app should be optimized for a mobile user, taking advantage of the natural qualities of the smartphone or tablet in any platform
Attractive - Your app needs to look amazing. Even the best app idea could falter if it isn't packaged in a fully branded, colorfully enticing way.
Easy - Your app needs to be easy to install, easy to access, and easy to use.
Unique - Make sure your idea is unique enough to stand on its own.
Memorable- Your user should be left with a major impression.
Shareable - The most successful mobile apps are the ones that are easily shareable. Your app needs to have a feature that rewards users for sharing it with other users.
Spontaneous - Any app needs to be accessible for short bursts of user activity. If your app only is good for long, drawn-out sessions of use, it probably won't succeed.
Cheap - The cheaper something is, the more users are likely to download it.
Demographic targeted - Know your audience. Not everyone in the world will want your app, so focus on the users who will.
Fun - Take the time to entertain your users.
