archviz delivery to mobile device?

Hi Guys,

we are currently working on an archviz project for mobile development aiming to do many individual projects for different clients. How is the best way to deliver?
Option 1: .apk per mail directly to client (Problem size of projects)
Option 2: embed project on homepage (how to setup that it works from mobile?)

Does anyone have experience?
Would really appreciate it!
Thanks!
