Split Screen Launcher

* Works with the latest Android 17

* No ads

* Pro unlocked free for 7 days

Split Screen Launcher lets you save your favorite app combinations as "pairs" and launch both apps at once in split screen (multitasking) with a single tap. No more picking and arranging apps every time — just create a pair and tap.

[New] SideEdge — a sidebar you can pull out from any screen

Swipe in from the edge of the screen and SideEdge opens, letting you launch a saved pair or a single app on the spot — no need to go back to the home screen. It's an ad-free sidebar that works on any Android phone or tablet, and you can adjust the handle's position, size, color, and transparency to your liking.

Miss launching split-screen app pairs from your old phone's sidebar? SideEdge brings that favorite feature back to any Android device.

Support the Developer

The free version saves up to 2 pairs and includes SideEdge, Drag-to-Split, dark mode, and all 15 languages at no cost. Everything else — unlimited pairs, home-screen shortcuts, folders, custom colors, reordering, Android Shortcuts, and backup & restore — unlocks with Pro. Upgrading to Pro keeps the app ad-free and supports continued independent development.

Thank you to everyone who supports this app!

Accessibility API Usage

This app uses the Accessibility Service for two purposes only:

1) To trigger split-screen mode on Android 9-12 (not needed on Android 12L and newer).

2) So SideEdge can automatically recognize login and password entry screens and hide its handle so it never blocks your taps (it restores automatically once you are done).

The service never reads, collects, or transmits any screen content.
