iOS offers different accessibility options, useful for people with disabilities, but not only. Some of these features can be hijacked to take advantage of them in everyday use, such as this trick to reduce the brightness below the minimum threshold. But who says accessibility also says control functions for use by a third party, typically a child. Many parents want to have a way to monitor the use of an iPhone or iPad by their child. In particular, let’s see how to limit the use of an iOS device to a single app. It’s actually about taking advantage of the guided access feature:
- Go to Settings > Accessibility > Guided Access

- Enable “Guided Access”

Thus, each time the user is in an app, it is possible to launch guided access by tapping three times on the Home button or the side Power button for iPhones without a Home button.

Once Guided Access is activated, various options accessible at the bottom left of the screen allow you to manage the settings (if you have activated the following option: “Accessibility shortcut” on the same page as the one used to activate the mode Guided access).

There is a timer in particular, but also the possibility of activating or deactivating certain physical or virtual controls.

But even more interesting: by launching guided access, you are asked to enter a code that will be useful to exit this mode, and therefore the authorized app.
Thus, a child can have fun in a game without being able to launch another app, on the iPhone or iPad. It should be noted that guided access will in all cases block the use of one and the same app, it will not be possible to open access to two or more apps.
Any (future) users of this tip?
