Google claim the "App Inventor" is a simple yet powerful tool which can use and manage databases, maps, web sites etcc. It also claim kids and students can develop their own apps.
It's pretty clear that Google is trying to make the whole app development very open, when rivals like Apple are more protective about it.
In the world of open source and its battle with Apple, Google's step doesn't surprise many. When Apple is way ahead of others in the app segment, google had to come up with some thing drastic so there are loads of android apps and app users on the market. So easy thing to do is get more and more people to develop them, but what about the quality? Would the inventor apps come on a par with professional apps? Does it not clog the market with loads of junk?
Well!! google's mantra seems to be make it a fun experience for mobile users. I will tell you what.. in case kids, students and public enjoy the tool and enjoy the whole experience of creating simple apps then its a big win for android phones and android apps!!! more and more android phones/apps and that means bigger market share for Google. God only save the professional app developers then.
