Its in Japanese, not French

This app is actually in Japanese, the INTERNATIONAL language of the sport of Judo. Judo, unlike other martial arts, is taught in Japanese, no matter which country it is being taught in. I can go to any dojo in the world and teach or (more likely) get taught, and understand what is being said. Using a common language and common rules is the primary reason Judo was the first Olympic martial art. As to what this does, it keeps time and score for a Judo match. Judo is much more popular in the US than many people believe.
