If your phone’s auto-rotate feature is a bit too sensitive, Smart Rotator allows for selective application-by-application rotation.
Many people turn off the auto-rotate feature on their phones because it flips the screen at awkward times. Smart Rotator allows you to specify which programs you want to rotate and which should stay in portrait mode. It’s a simple application that stands to save a lot of frustration. You simply install it, flag the apps you want to rotate, and it runs in the background automatically toggling the auto-rotate feature based on which apps are in focus.
Smart Rotator is a free app, Android 1.6+.
