How to Kill an App on iPad / iPhone

Apple introduced multitasking with the iPhone 4 and iOS 4.0. Multitasking on the iPhone or iPad allows you to have apps paused in the background so they are easy to switch back and forth to. IOS 8 has now changed the process of closing an app that is running in the background. In this how-to article, we’ll show you how to close the apps running in the background on any iOS 7 or above device:

How to close an app on the iPhone and iPad:

1. Double-tap the Home button on your iPhone or iPad.
2. This will pop up the multitasking app view, where you can scroll left and right to view the apps that are running.
3. Swipe the app window up to close the app.

Now you can open the Vagaro Pro app without any issues.
