Okay, for when you need to close one—because you do, sometimes. Let’s break it down by your iPad model, because Apple loves to mix things up.
For iPads with a Home Button (the old-school kind)
Double-click the Home button fast. Like you’re giving it a little double-tap of trust. You’ll see all your open apps as a stack of cards.
Now, swipe up on the app’s preview to throw it away. It’s oddly satisfying, like flicking a playing card off a table. Do this only for the one or two apps that are misbehaving.

For iPads without a Home Button (the modern Face ID era)
This is the gesture party. Slowly swipe up from the very bottom of the screen and pause in the middle. Don’t flick—pause, like you’re waiting for a punchline.
You’ll see the app switcher appear. Then, just swipe up on the app you want to close. Pro tip: Use two or three fingers to swipe multiple apps at once if you’re feeling rebellious, but remember: you’re probably creating more work for your battery.
