Your iPhone is a little different from your computer for the fact that your computer can simultaneously have multiple apps open and running at the same time so that you can easily switch between them. The iPhone can also have more than one app open at a time, at least for a few moments, but will typically terminate apps that haven’t been active for a while in favor of supplying the phone’s resources to other apps that need them.
But occasionally an app will malfunction or get stuck, leaving you to look for a way to turn that app off on your iPhone 7. Our guide below will show you how to turn that app off by using something on your iPhone called the App Switcher.
How to Force Close an App on an iPhone 7
The steps in this article were performed on an iPhone 7 Plus, in iOS 10.3.2. The result of completing these steps is that you will have closed an app on your device. Apple does not recommend doing this, and iOS generally does a good job of managing which apps are using the phone’s resources. However, if you are using an app and it gets stuck, or if you suspect that your phone is operating slowly because a specific app is not closing or turning off properly, then this method will allow you to turn that app off completely.
Step 1: Double-tap the Home button under your screen. This is going to open the App Switcher, which lists the apps that were most recently open on your device.
Step 2: Swipe left or right to scroll through your recently open apps until you locate the app that you want to turn off, then swipe that app towards the top of the screen.
You can then continue swiping any apps toward the top of the screen that you wish to close as well. Once you are done you can press the Home button under the screen to exit the App Switcher. Note that you can also use the App Switcher for multitasking purposes, as selecting one of the apps there will let you switch to that app.
One other way that you can manage a mis-functioning app is to uninstall it, then re-install it. This guide will show you how to delete apps on your iPhone, as well as how to delete some other files that might be using your iPhone; storage.
