Letting a child use an iPhone often starts with one simple task: watching a lesson, checking a message, taking a photo, or using a learning app. But the device has many other entry points, and children naturally explore.
The first boundary is app installation and deletion. This keeps the phone stable and prevents accidental changes to the home screen or app list. The second boundary is around store actions and in-app flows that may distract from the original task.
Content access is another important area. Age ranges, media categories, multiplayer games, adding friends, and Siri can all be useful in some contexts and distracting or risky in others. These settings should be easy to adjust for the current moment.
iPhone Locker is designed to make these boundaries visible and repeatable. Instead of checking the whole phone every time, you can prepare a child-use setup and switch into it when needed.
