If it's still on your iPhone, it should show up near the top under Applications. If the app is not currently installed on your iPhone, it may show up under the App Store heading instead. If so, tap on "View," then the cloud button to quickly redownload it. If you see "Get" instead of the cloud button, then you've never installed the app before on any of your devices.
However, if you see "Open" instead of "View" under the App Store heading, that most likely means you are restricted from accessing the app see Step 2 below. If an app isn't appearing under Applications or App Store in Search, it doesn't mean it's not on your iPhone at all.
When an app you're looking for appears under the Settings heading instead, that usually means the app is hidden from Search. If it is and it says "Off," tap on it and toggle on both switches. Aside from these Search tips, you can also go right to the Settings app and see if it's listed there. However, like mentioned above, not all apps have iOS-specific settings, so it might not show up there anyway. A better way is to go the App Store and search for it there.
Camera App is Missing from iPhone or iPad
If it says "Open" next to it, it's on your device somewhere. If you share an iPhone with family or you're using one with a management configuration profile installed on it by either your parents, school, or work, then they could have restricted access to the app you need for some reason. They can restrict any third-party apps by age , as well as hide Apple apps such as Safari, FaceTime, and Podcasts.
These apps may still appear in Search, but you won't be able to open them or their settings. Some apps no longer work in iOS 11, those that are only bit compatible and haven't been updated yet. So if they're missing on your device, you might as well forget about them for good. If you try to find them in your list of previously purchased apps in the App Store , you'll see them, but won't be able to download them anyway.
