This will probably seem like a dumb noob question to a lot of you, but- why would anybody bother to create an app and give it away free? Being mostly computer illiterate I am amazed every day by what it must take to make (or is it write?) an app, and at the number of truly useful and amazing apps I've gotten for free! Heck, even the ones that are a buck or two seem to be a steal. I reasoned that somebody might make an app and sell it for a buck thinking an economy of scale- that there are so many people in the market that even at a buck per that might add up to a big payday if the app takes off; but I can't understand why someone would put in all the effort to think up, design, build, and publish an app- for free. Yet as we know, there are tens of thousands of free apps, some that are downright amazing! I'm sure some of you real smarties are laughing at this dummy (and I'm OK with that!), since obviously there's got to be an explanation that makes sense. I just can't think of what that would be? Education appreciated!
