Kinvey, backend service for apps, released this infographic based on conversations with 100 app developers.

“Of course, there’s a subtext to this graphic. Specifically, it doesn’t have to take 18 weeks to build v1 of your app. It can take a lot less time. The backend alone is estimated to require 10 weeks, but a backend as a service like Kinvey can dramatically reduce that time,” the company says.

Another thing to keep in mind before you go off and make an app: Most don’t make money.
