Guided Access is an accessibility feature in iOS that allows to you to lock an iPhone or iPad to one specific app. As long as Guided Access is enabled, only that one specific app can be used, and there's no way to exit it for the Home screen or any other app. Guided Access can be extremely useful in education settings, to help kids focus for learning math, language, and other skills, and for working with people on the autistic spectrum. Guided Access can even be used to create a "guest mode" so you can hand your device to someone and let them use Safari, iBooks, Video, or a game without having to worry about them snooping through your personal information. All you've got to do it set it up and activate it!
How to enable Guided Access
Launch the Settings app on your iPhone or iPad.
Tap on General.
Tap on Accessibility.
Tap on Guided Access under the Learning section.
Toggle Guided Access On.
Tap on Set Passcode and choose a passcode that only you will know.
Toggle Accessibility Shortcut to On so you can triple-click the Home button to enter Guided Access from wherever. You only have to complete this step if you choose.
How to use Guided Access
Launch the app you'd like the intended user to have access to.
Triple click the Home button to launch Guided Access.
Circle any areas of the screen you wouldn't like to be accessible, if any.
Tap on Options in the bottom left to choose whether or not you want to grant access to the Sleep/Wake button, Volume buttons, touch screen, and motion. Tap Done to save your selections.

Once Guided Access is enabled, anyone trying to leave the specific app you've locked it to will receive a banner message telling them to triple-click the Home button to exit. If they don't know the passcode, they won't be able to exit Guided Access unless and until you enter the passcode.
If you've used Guided Access on your iPhone, iPod touch, or iPad, what do you think of it and why do you use it? Are there any improvements you think Apple could make that would allow it to be even more useful for you?
