After some time playing the game I must say that it is really good and I recommend it to everyone. It is still in alpha phase, but is updated very often, with each update bringing new stuff like buildings, interface updates and mechanics updates. Also, TheoTown looks a lot like SimCity 2000.
You can build zones (RCI), provide your citizens with water, power, education, healthcare etc. There is a lot of attention to detail, like showing pollution in your industrial zones, sparkling of the water, smoke from the chimney and more!
You can download the app on your smartphone and tablet here: https://play.google.com/store/apps/details?id=info.flowersoft.theotown.theotown
And this is the official site (unfortunately for some, it is in German): http://www.theotown.de/forum/portal.php
This is what the description says:
