I just found out that students enrolled at accredited universities can get a student discount for a MonoTouch Pro license. You’ll only have to pay 79$!
Get one, the price point is really really low. For comparison, a Unity license for iOS is 400$ per platform, Corona is 199$, Marmelade is 149$ per platform, etc. That makes libgdx by far the cheapest (free for desktop, Android, browser, 79$ for MonoTouch on iOS) of the managed solutions. C++ frameworks like Cocos2D-x or Gameplay SDK are of course without any kind of cost. They don’t work in the browser though. So pick your poison.
Note that you’ll also need an Apple developer account, which is 99$/y. You’ll need that for any option if you want to publish on the App Store.
Also note that you don’t have to get MonoTouch to test your app in the simulator.
We’ll try to get iOS support into gdx-setup-ui and our build asap so you can start playing around with it. It’s still a little rough around the edges, but we got a lot of games running already.
