Is really easy to configure, let you choose and customize lot of parameters and specs from the virtual android device (virtual machine).

What I like the most about Geny Motion is that it has the power to emulate so many different kinds of mobile devices from different manufacturers like Google Nexus, Samsung, HTC and more. This makes it easy to test an application on multiple phone types while using on software.

I use Genymotion for a long time. Best is that it does not consume much memory compare to Native Android emulators.
