Screen is described as 'multiplayer screen sharing app that lets you work together like you’re in the same room. Unlike videoconferencing tools that are designed for presentation, Screen lets everyone participate through multiplayer drawing & control' and is an app in the Office & Productivity category. There are eight alternatives to Screen for a variety of platforms, including Mac, Windows, Linux, Online / Web-based and Google Chrome. The best alternative is Visual Studio Live Share, which is free. Other great apps like Screen are Teletype (Free, Open Source), Drovio (Freemium), DeskShare (Paid) and Floobits (Freemium).
With Drovio, you can invite who you want on your screen, they all get their own mouse cursor appearing on it and can interact with your apps in real time, making you feel you are no more alone on your desktop!
CoScreen turns your extended screen into a remote collaboration platform. The app provides an entirely new remote collaboration experience through simultaneous multi-user screen sharing, remote control and audio chat.
