Ansca Mobile's Corona will fundamentally change how you approach iOS and Android software development, whether you're an engineer, a web developer, or a designer.
The Corona SDK allows you to rapidly create native applications and high-performance games for the iPhone, iPad, and Android. You get full access to device-specific features such as the camera, keyboard, GPS, accelerometer, video playback, audio recording, multitouch input and embedded web views. Your application will automatically leverage the performance benefits of being a native executable, especially hardware-accelerated OpenGL graphics and sound.
