Can I test my VR game without OR or GearVR?

Hi, I’m trying to make a VR game for Android, with something like the google cardboard. All I need is to let the phone display in stereo mode. I can do this on my computer, using the SimpleHMD , I can see how it goes in VR preview. But when I package it and install it on my phone, it’s still non-stereo.

This message prompts up every time I launch the app. So I’m guessing maybe I have to install SimpleHMD on my phone? But I couldn’t find it anywhere… Can anyone help?
