Solution for me==> When going to the Samsung Galaxy App Store, the phone was always choosing "Phone." I saw there was also a "Gear" choice that I had to manually select. After the right combination of choices, I was able to get my phone to go to the "Gear" side of the Samsung Galaxy App Store and I was able to download Facer Companion for Gear.
Hope this helps someone. Who knew that you had to force over to "Gear" to get the "Gear" side.
