D20 스마트워치 밴드 사용방법과 hryfine 앱 모든 사용방법 hryfine App tutorial 초등학생스마트워치

I'm trying to test the D20 smartwatch for its value, but I don't know how to use it. I'm not entirely sure what the hryfine app is, so I've been searching and testing it out, and I'm posting the instructions. Actually, you might think this is more about using the hryfine app than the smartwatch itself. There's not much information about the hryfine, and since it's a smartwatch that requires the app to really get the most out of it, I'm posting this as a side note. With a good understanding of the information, I think you can get a lot out of it for the price. If you can't use it, it's just another Apple watch. Haha.
