What does Android version cost?

[muppets4 24]

I'm introducing a friend to my Emby server. Can I simply buy her the app and start playing from my server? Or does she need a premiere too?

 

And because I allready bought it I cannot see the price. What will it cost?

 

Edit: no need for premiere and a free app. Great!
