I am considering a purchase of the pro version.  I would like to use it as an "app" for my photo clients.  However, I am hoping that someone can explain to me how it works when sending a link.  If someone opens it on there a device, is there some sort of trigger to ask them to add it to their home screen?  I can do this my selecting my options in my browser but I would like a trigger because many users will not understand how to do this.

Is this already a feature that I can activate?  Could someone share a link with me of one of their galleries so I can see what a client might experience?

Thanks
