Overview

The Real-Time Whiteboard App is a fun and easy-to-use tool that lets people draw, write, and add emojis together on the same screen from different locations. Whether you're in a class, a meeting, or just brainstorming with friends, you can all join the same session and see changes live. The app supports different pen styles, colors, background changes, text, and emojis. You can even download your final drawing as an image. With Firebase, everything stays in sync instantly, and AppsFlyer makes it easy to share a session link with others. It works on both mobile and web, turning your screen into a shared creative space for learning, planning, or just having fun together.
