This infographic will walk you through the legal bases you need cover for each step of app development.
We've all had our ideas for apps. What if you could fling enraged songbirds at smug farm animals? Doesn't that sound awesome? Someone should get on that. They'll need this guide though, because the legal system is not simple, and if they miss any one of these steps they might well be kicking themselves further down the road.
