You can now download and use android apps like whatsapp, subway surf, LINE, wechat, in fact all android apps and android games on your pc using the android emulator software for personal computers. Popular ones are: Bluestacks, www.bluestacks.com and MEMU, www.memuplay.com . But you need at least 2-4gb of ram and about 8gb free space on your hard drive and other specs. I was using bluestacks and it has little hitches, but bluestacks is the widely use software, i started using MEMU for about a week now, though they claim on their site that the software dont crash and better than bluestacks. The android emulator software is available for most operating systems, windows, Mac, Linux.

MEMU comes with playstore app so you can download android apps directly on your emulator.

Bluestacks comes with Bluestacks tv option where you can watch others live who are playing MMO and RPG games on bluetacks.
