There are several systems to emulate Android on PCs with Windows or Mac, as Genymotion or Bluestacks, but recently appeared an interesting new competitor: Andy.
Andy is a tool to run Android applications on Windows / Mac within a virtualized environment of Android, where you can download the apps they want from the Play Store and work as if our smartphone or tablet is involved. You can use Whatsapp or Android games and using a mobile as joystick. And it is very easy to use because it is intended for the average user, rather than technical.
Andy simulates a tablet with Android 4.2.2, with the necessary tools to run applications for mobile and communications as WhatsApp, Viber and Snapchat modifications. Also, for use with the games, you can connect and detect your smartphone for using its sensors, control movements. Optimal to manage without the limitations of display or storage space. You can also synchronize the data in a phone with this "virtual tablet" via Google and 1ClickSync.
The installer download the full package, stodgy, since it is the operating system + virtual environment + basic apps, but does not require us to be a genius to do it. After starting the system, we have a virtual Android tablet ready to use, so just connect it to a Google account and you can download everything you need.
The system once, displays the three classic Android buttons (go back, go to the main screen and options) loaded. And of course, allows several modes: full, horizontal and vertical screen.
It is interesting for those who just want to try an Android app without having to download it to your own device, or for users of iOS who want to try the Android experience, even for those who just want to install a heavy game and have no option enough space on their phones or tablets.
