The Calculator App is a Built-in App that comes pre-installed on most iPhone devices. It can perform simple calculations and be uninstalled like any other app. However, if the Calculator App is missing from your device, you may wonder how to get it back and why it disappeared.

Possible reasons for the Calculator App’s disappearance
Accidental deletion
iOS makes it very easy to delete your installed apps accidentally, and the Calculator App is no exception. If you recently deleted it by mistake or are using a new iPhone that was reset to factory settings, you can quickly restore it in just a few steps.
Restore a built-in app such as “Calculator” that you deleted:
1- Go to the App Store on your iPhone or iPad and search for the Calculator app by typing its name into the search bar. Make sure that you use the exact name of the app.
Note:Â You might find many other calculator apps available in the App Store, but to restore the iOS native Calculator app that was previously deleted, you need to find and download the correct version. It should be labeled as “Utilities.” Beware that the App icon should be the same as the picture below.
2- Tap on the result that matches the name of the Calculator app, then tap on “Install” or “Get” to restore it to your device.
3- Wait for the app to be restored.
Relocation to a different home screen or folder
There are a few ways that the Calculator App (or any app, for that matter) could be relocated to a different home screen or folder on your iPhone:
- Accidental drag and drop: If you tap and hold on an app icon, you can move it around on your home screen or into a folder. If you accidentally drag the Calculator App to a different screen or folder while rearranging your home screen, it could end up in a place where you don’t expect it to be.
- Sorting apps: If you have a lot of apps on your device, you may have sorted them into folders or rearranged them on your home screen to make them easier to find. If you have sorted your apps this way and need help finding the Calculator App, it may have been placed in a different folder or on another screen.
- Automatic sorting: Some iPhone users may have enabled automatic app sorting, which rearranges their apps based on usage or other criteria. If you have automatic app sorting turned on and can’t find the Calculator App, it may have been moved to a different screen or folder.
In any of these cases, you can look in other screens and folders to see if the Calculator App has been moved to a different location. If you still can’t find it, it might be the case that you accidentally deleted it or that it has been removed as part of an iOS update. Either way, you will need to restore it from the App Store following the instructions above.
