I only got the app Tiny Tower on my iPad today and I've already spent ages on it. It is really fun as well as being needier than an Oceangotchi. The idea is that you build a skyscraper thing with shops, cafes, arcades and accommodation for virtual people employed there. You can choose which job to give each person based on their skill level at each job. *gets notification saying my barber shop is ready to be restocked* It constantly sends you notifications, like it just did. You have to buy new stock for your shops and stuff when it runs out. If you don't have Tiny Tower, I recommend it; it is free and looks like it's compatible with almost all iOS devices.
