I'm no developer, but I've started to see on the news lately about Apps, that let parents set tasks for their kids, and in return, the kids can earn credits, be it pocket money, time on the internet etc.....

Imagine an App installed on the parents phone, and also on the kids tablet / phone, where the parents can set the tasks (clean bedroom, do homework etc) and in return, when the tasks are completed, the kids are rewarded with piggycoins.

Just a thought.....
