With Samsung, ASUS, LG and numerous third-party apps adding floating windows or split-view modes to Android, Google’s OS now lets you view two or more applications on screen at the same time. With the right software, users can check email on the left side of the screen while surfing the web on the right or play a video in a translucent window on top of their work. Having the ability to see more than one program at a time makes users more productive and allows them to use something in one window (ex: a web site) that they make use of in another (a document editor).
The iPhone 5s’s iOS 7 operating system doesn’t provide any way to run apps side by side. Considering the way that Apple handicaps developers by sandboxing apps, it’s unlikely that anyone will be able to write a third-party utility to enable multi window.
