About this app

* Works with the latest Android 17
* No ads

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.

Common Uses
Photos + Music: Browse your photos while music plays
Video + Social: Watch YouTube while checking Instagram
Research + Notes: Search in Chrome while jotting things down
Work + Comms: Keep Gmail and Slack side by side
Compare + Calculate: Put your browser next to a calculator
Navigate + Chat: Check your route on Maps while sending a message

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.

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.

Ratings and reviews

This app just works! No server-side, data mining. The developer is very attentive and is open to feature requests. I requested a new feature and a day later it was there in an update. Get the "Pro" version!

Wow, actually great, cuz it has no ads and it's very simple to use, nice UI. thanks for responding lol. can you fix this small issue? basically when I open the app and try changing my colour to default, it glitches a bit.

best app for split screen it worked on my Redmi A3,Redmi A3 does not support split screen
