InstaLauncher is a system-wide application launcher for iOS. It lets you launch appliactions in under 500ms, even less if you use its favourite menu. You can read more about it here.

For a detailed review, both in text and video, made my iDownloadblog you can go here.

You can watch it in action on youtube. Or you can check out some very old pictures of it while I was just starting to build it here.
