RotaGesture

RotaGesture allows you to control the orientation of your Android device with a two finger swipe gesture. The gesture allows you to naturally "spin" the screen, making RotaGesture the fastest and easiest way to move between locked orientations.

If you find yourself locking the orientation because you often lie down sideways to browse the web, or send a text message, then this app is for you. Alternate between landscape and portrait (and their respective reverse views) orientations by sliding the edge of the screen up or down. The optional lock setting allows you to hold a rotation you may not have been able to with stock Android.

The gesture can be set on the right and bottom edges relative to the current screen. If your device is having trouble recognizing the gesture, you can configure the activation area size in the settings.
