"Most apps take at least six months of full-time work and cost between $20,000 and $150,000 to develop, according to Forrester Research" So here the strategy is simple: just develop stupid things that takes a few days. If you check the top apps, half are not hard to code at all but stupid things that people are willing to buy. So instead to write a smart, interesting application that costs 100,000$ it's better, I think, to write 20 applications costing 1000-3000$ each.
