How to view Stereo Panoramic images on google cardboard

Hi everyone

I am a very new comer URE4 (architect by trade) have been learning my way around Stereo Panoramic images and videos. But im slightly lost as to where to look for information about how to then view these images on a smart phone. I basically want to give me clients a simple 360 image to look around in on a google cardboard.

Apologies if this is confusing. Any help would be greatly appreciated.
