What is Corona?
Corona SDK is a product by Ansca Mobile for the creation of games for iPhone, iPod Touch, iPad, and Android devices. At the time of this writing, there is a free unlimited trial version of the kit available here. It includes all of the functionality of the paid version, except for publishing to respective app stores of the iPhone and Android devices.
Corona was built from the ground up for blazing-fast performance. Built on top of OpenGL, OpenAL, and Lua, Corona uses the same industry-standard architecture as top-selling mobile games from Tapulous, Electronic Arts, and ngmoco.
Corona’s framework dramatically reduces your coding. Tasks like animating objects in OpenGL take only one line of code. And your code instantly updates and reruns in the Corona Simulator, for rapid testing without lengthy build times.
Corona makes it simple to use gaming features like sprite sheets, Box2D physics, Facebook Connect, and OpenFeint social gaming. Corona games run at native speeds, and significantly outperform apps developed in web-based technologies like Adobe Flash, Appcelerator Titanium or GameSalad.
Use native iOS and Android features like multitouch, GPS, accelerometer, camera, Google Maps, WebKit, software keyboards, and more — it’s all available in Corona. Access social networks like Facebook and Openfeint and services like mobile analytics, with much more coming soon!
