I find I'm in a similar mindset. What I've found is that once I stop learning, things become boring. Yes, I know I can take that interface, hook it up to this database, and with a bit of logic glue make a wonderful app come alive. The only challenge in that kind of work where you already know how to do every piece is overcoming the sheer boredom from going through the motions.

So what I think is the solution is to go meta. Step back and ask why you're having to write the same code to pump out the same kinds of apps. What is the commonality between all the various apps you're writing? Now solve that problem. The ultimate iteration of this, if done successfully, is a system that takes a design plus a formal specification of an app's functionality and automagically makes it work. Now you're working at a higher level of abstraction. I don't yet know what happens when you get bored of that. Perhaps by then you'll have developed your own AI.
