Have to have a Computer on your network if you want to use your personal music library. However, you can use your android phone or iPhones to use the app anyway you want also.
Once you set it up, it's a piece of cake to use it. Took me less than 5 mins to set up mine. The good thing is that you have the ability to have different music in each room or the same, with different units. You can also control the volume of each unit from the app. Hope this helps.
