This app is an open source app, and anyone can create it by downloading the source from the channel "Beginner Archer" and watching the video.
If you have your own Youtube video, you can classify it in the form you want, and if there are other SNS sites under management, you can link and distribute them together.
You can also put in 3 types of advertisements, so try to get a small margin.
