I'm making a billiards app for smartphones. The video you are watching contains content from the billiards textbook I created. I also include content played by world-famous professional billiards players in my textbook.

Do you have a billiard table?
If so, try installing the billiard practice system (BPS: Billiard practice system) I created. You can practice by projecting the contents of the billiards textbook directly onto your billiard table. If you are interested in BPS, please refer to the following link.

For inquiries about purchasing billiards textbooks (apps, e-books) and BPS made by Billiards Doctor, as well as sponsorship and advertising inquiries, please contact the following.
