Now that you know how to open the multitasking screen by double-clicking the home button, it's quite easy to switch between apps on your iPad. And if you have multitasking gestures turned on, you don't even need to open the new task screen. Switching between apps is a great way to increase productivity.
Swipe to Switch Between Apps
You can navigate the multitasking screen by swiping left or swiping right to move between apps. Remember: a "swipe" is tapping your finger against the screen and keeping it pressed against the display while you move it left or right. This will move the carousel of apps.
Once you've found the app you'd like to activate, simply tap it with your finger and you will go into the app. If you were recently using it, you should pick up where you left off, though not all apps support resuming. Some apps, especially some games, must relaunch to correctly be used.
The Multitasking Screen is a Great Way to Launch a Recently Used App
Remember, you don't need to be switching between two apps to use the multitasking screen. Even if you haven't launched the app for hours, it will still be on the list if you haven't opened too many apps since you last used it. This makes the multitasking screen a great way to find and launch frequently used apps.
Switching Between Apps With a Gesture
If multitasking gestures are turned on, you don't even need to open the multitasking screen to switch between two apps. Using either four or five fingers, you can swipe left or right to move between apps in full screen mode. Remember, at least four fingers need to be on the screen when you swipe it for this to work. It takes a little practice, but once you are used to it, this gesture is a great shortcut for going back to your last used app.
You can also launch the task screen by swiping upwards on the screen using at least four fingers. So if you can't find the app you want by swiping left or right, you can do a quick swipe up to get a better view of your open apps.
