This is definitely one of the stranger apps of the bunch, but at least it tries to communicate a message. With the iHobo app, your job is essentially to look after a young homeless person for three days—which includes virtually providing food, money and shelter. But your duties stretch beyond those basic needs; your actions affect his moral decision as well. “And the speed of your response could be the difference between him making it through in one piece, or becoming addicted to drugs,” the app description reads. It’s not your run-of-the-mill mobile game, but there’s definitely a charitable theme behind this one.
