Dattrax Kade (Free version)

Simply download this app, hook it up to your account on the web, and play your games on your phone or tablet! This is a great tool to get started programming with. Developed to introduce you to the basics of programming.

Many development environments fall into two categories - they're either simply drag-drop "graphical" environments that don't really introduce you to software development in any meaningful way, or they're professional, object-orientated coding languages that are way to complex to get started with.

Kade hits the middle-ground, allowing you to quickly develop neat programs that teach you about using "for-next" loops, "if-then-else" logic, "while" loops, and so on. Not only that, but it's designed to build games, with a full graphics engine built in.

The Free version of the app only allows a maximum of 2-minutes per run of your game, so you can get a feel for it working, but that's it. It also limits you to adding one "non-public" developer; ideal for you, but limits your ability to easily play games from your friends. No worries - just buy the Full version of the app and these limits are gone.
