I can't download the Facer Companion app- I've done everything I can and no luck

I’m just trying to get the Animal Crossing watch face and it’s turning into a fiasco. I have a Samsung Gear 2 (it’s a bit aged- my boyfriend gave it to me). I figured it would be okay, because it’s on Tizen 2.2 (apparently) as far as I can tell I should be good to go, but I can’t find the dang app.
