If you spend your day copying details from one window into another, learning how to use split screen can save you a surprising amount of time. Split screen simply shows two apps side by side on the same display, so you can read on one side and write on the other without switching back and forth. It works on most modern phones and computers, costs nothing, and takes only a few minutes to learn.
Key Takeaways
- Split screen puts two apps side by side so you stop switching windows all day.
- On a computer, drag a window to the edge of the screen or use the built-in snap shortcut.
- On Android, open recent apps and choose the split option; iPhones need a different approach.
- Pair a reference app with a working app, and keep both sides free of distractions.
How to Use Split Screen on Windows and Mac
On a Windows computer, the fastest way is to drag a window to the left or right edge of the screen until you see an outline, then let go. The window fills that half, and Windows shows your other open windows so you can pick one for the other half. You can also click a window and press the Windows key together with the left or right arrow key to snap it to one side.
On a Mac, move your pointer over the green button in the top-left corner of a window, then choose Tile Window to Left of Screen or Tile Window to Right of Screen. Click a second window and it fills the other half. To leave split view, move your pointer to the top of the screen and click the green button again. If the Tile options do not appear, your Mac may need a newer system version, or the app itself may not support tiling.
How to Use Split Screen on Android and iPhone
On most Android phones, open the recent apps view by swiping up from the bottom of the screen or tapping the square navigation button. Tap the app icon at the top of the first app’s preview and choose Split screen. Then tap a second app, and the two share the screen with a divider you can drag to give one side more room. The exact wording varies slightly between phone makers, but the steps are the same in principle.
iPhones do not offer a system-wide split screen for two apps, so do not waste time looking for the setting. If you use an iPad, it does: open one app, then drag a second app from the Dock to the side of the screen. On an iPhone, the closest options are switching quickly between apps with the app switcher, or using picture-in-picture to keep a video floating while you work in another app. For real side-by-side work on the go, an Android phone or a tablet is the better tool.
Good Combinations for Everyday Tasks
Split screen works best when one side holds your reference and the other holds your work. Keep your notes open on one side and the document you are writing on the other. Follow a video call on one side with its agenda on the other. Compare two products, two timetables, or two versions of a document without losing your place in either.
It also pairs well with other simple setup upgrades. If you find yourself splitting windows every day, learning how to set up a second monitor gives you even more room, and the keyboard shortcuts that save time make snapping and switching windows faster still. When your work lives in the browser, it helps to organize your browser tabs first, so the two tabs you need are easy to find.

When Split Screen Helps Less
Split screen is not always the answer. On a small phone screen, two apps side by side can feel cramped, and reading tiny text gets tiring fast. In that case, use one app at a time and switch with the app switcher instead. Two demanding apps at once can also slow an older device, so close anything you are not using.
There is a focus cost too. A second window full of messages or a social feed can pull your attention away from the work on the other side. If you notice yourself checking the second app more than working in the first, the split is hurting rather than helping. Close the distracting side and keep only what the task needs.
Fix the Common Problems
If an app refuses to split, the app itself may not support it. Some video and banking apps block split screen, and there is no setting that forces them. Try a different app for that half of the screen. If the divider will not move, drag it slowly from its centre handle. If the text looks too small, turn the phone to landscape orientation, which gives each app a wider column, or move the divider to give the reading side more room.
If a window snaps back to full size, you may have dragged it too far or released it before the outline appeared. Drag again more slowly and wait for the outline. And if split screen disappears after an update, check the steps again: phone makers sometimes move the option to a different menu, but the feature itself rarely goes away.
- Drag a window to the screen edge, or use the snap shortcut, to split a computer screen.
- On Android, choose Split screen from the recent apps view; iPhones have no system-wide split screen.
- Pair a reference app with a working app, not two distractions.
- On small screens, switch to landscape or use one app at a time instead.
What to Watch Next
Start with one everyday pair, such as notes beside a document, and practise snapping windows on your computer or splitting apps on your Android phone. Keep the reference on one side and the work on the other, fix any app that refuses to split by swapping it for one that does, and drop the split whenever the screen feels cramped or distracting. Once the habit is set, split screen should quietly remove the constant switching that eats into your day.
