“If you build it, they will come.”  Well, not exactly. The actual quote is “if you build it, he will come,” and in today’s hyper-competitive marketplace, just building something isn’t going to get anyone to come to you. And once they come, you need to get them to stay.

It isn’t an easy process. That’s why there are millions of apps in the app store today, and only a small fraction of those apps are used on an ongoing basis. In fact, 80-90% of mobile apps are used once and then deleted.

The infographic below outlines some of the key insights we’ve learned, and highlighting some suggestions for things to look out for in building your optimized app:
