How Do You Close an App on Any Device?
Closing an app sounds simple — and usually it is. But depending on your device, operating system, and what you're actually trying to accomplish, "closing" an app can mean several different things. Understanding the difference matters more than most people realize.
What Does It Mean to "Close" an App?
There's a practical distinction worth knowing upfront: suspending an app versus terminating it.
When you navigate away from an app on a smartphone or tablet, most operating systems don't actually quit it — they pause it in the background. The app still occupies a slot in memory but isn't actively running processes. This is by design, meant to make switching between apps feel instant.
Force-closing or force-quitting an app goes a step further. It removes the app from memory entirely, stops all background processes, and resets its active session. This is what most people mean when they say they want to "close" an app properly.
How to Close Apps on iOS (iPhone and iPad) 📱
Apple's iOS uses a gesture-based app switcher.
On iPhones with Face ID (iPhone X and later):
- Swipe up from the bottom of the screen and pause briefly in the middle
- The app switcher opens, showing open app cards
- Swipe any app card upward to close it
On older iPhones with a Home button:
- Double-press the Home button to open the app switcher
- Swipe up on the app card you want to close
One thing worth knowing: Apple's official guidance has long been that closing apps manually on iOS doesn't typically save battery life and can sometimes slow things down because the OS has to fully reload the app next time. iOS is optimized to manage background apps on its own.
How to Close Apps on Android
Android varies more than iOS because manufacturers often customize the interface, but the general approach is consistent.
Standard method:
- Tap the Recent Apps button (usually a square or three-line icon at the bottom of the screen, or a gesture swipe)
- Swipe individual app cards left or right — or up, depending on your device — to dismiss them
- Many Android devices also show a "Close All" button to clear everything at once
Force-stopping from Settings: For apps that are misbehaving or won't close through the switcher:
- Go to Settings → Apps (sometimes "Application Manager")
- Select the app
- Tap Force Stop
This is a more aggressive close and is useful when an app is frozen or draining battery in the background.
How to Close Apps on Windows (PC)
On a Windows computer, apps can be closed in several ways depending on how they were opened and how they're behaving.
| Method | How to Use It | Best For |
|---|---|---|
| Click the X button | Top-right corner of the window | Normal, responsive apps |
| Alt + F4 | Keyboard shortcut | Quick close without touching the mouse |
| Right-click taskbar icon | Select "Close window" | Apps minimized to the taskbar |
| Task Manager | Ctrl + Shift + Esc → End Task | Frozen or unresponsive apps |
Task Manager is the Windows equivalent of a force quit. If an app has stopped responding, right-clicking it in Task Manager and selecting End Task terminates the process immediately.
How to Close Apps on macOS (Mac) 🖥️
On a Mac, clicking the red circle (close button) in the top-left corner of a window often doesn't quit the app — it just closes the window. The app itself keeps running in the background, which is standard Mac behavior.
To actually quit an app:
- Press Command + Q while the app is active
- Or go to the app name in the menu bar → Quit
For unresponsive apps, use Force Quit:
- Press Command + Option + Escape to open the Force Quit window
- Select the frozen app and click Force Quit
Alternatively, right-click the app's icon in the Dock and select Force Quit if the app shows as "not responding."
Does Closing Apps Actually Help Performance?
This is where things get nuanced — and it depends heavily on your device and OS.
On smartphones: Modern operating systems (both iOS and Android) are built to manage memory dynamically. Regularly force-closing apps can sometimes work against you, because the OS has to do more work loading apps from scratch instead of resuming them from a cached state.
On Windows and macOS: Apps don't enter a "suspended" state the same way mobile apps do. A running desktop application is actively using CPU, RAM, and potentially network resources. Closing unused desktop apps more reliably frees up system resources — especially on machines with limited RAM.
When force-closing clearly helps:
- An app is frozen or unresponsive
- An app is misbehaving and consuming abnormal battery or CPU
- You want to fully reset an app's session (clearing a login, restarting a sync process, etc.)
The Variables That Shape Your Situation
How you should close apps — and whether it matters — shifts based on factors specific to your setup:
- Your OS version: Newer OS releases handle background process management differently than older ones
- Your device's RAM: Older or lower-spec devices may benefit more from closing unused apps
- The app's behavior: Some apps are better-optimized for background suspension than others; some have known bugs that require periodic restarts
- What you're trying to fix: Performance problems, battery drain, and app crashes each point toward different approaches
The mechanics of closing an app are consistent across devices. What changes is whether doing so actually achieves what you're hoping for — and that depends almost entirely on your specific device, OS, and the behavior of the app in question.
