Limit an iOS Device to Running a Single App

Apple has introduced Guided Access in iOS 6. It keeps your device in a single app and allows you to control which features are available. 

Locking a mobile device into a single app has been a request of parents and educators for some time. Using Guided Access to limit an iPad, iPhone, or iPod touch to one app can be handy when you want a child to remain on task and focused. It is also nice for youngsters who might accidentally click the Home button.

To start Guided Access: 

1. Launch the Settings App.
2. Go to General and choose Accessibility.
3. Turn Guided Access On.
4. Set a passcode.
5. Launch the app you want lock the device into.
6. Triple-click the Home button.
7. You can choose to disable touch or motion in addition to disabling the Home and volume buttons.
8. Tap the Start button.

To exit the app, triple-click the Home button and enter the Guided Access passcode.

iOS 6 is now available as a free upgrade for iPad 2, iPad 3rd generation, iPod touch 4th generation, and iPhone 3GS and newer.
