This application was born from my experience as a Taekwondo instructor, in contact with students, beginners or confirmed, parents ..., I could see that they all needed an instrument within their reach allowing them to " review "the teaching received during the course and assimilate the main points.
The application that I propose to you is in fact a practical guide, with many illustrations and simple and concrete explanations.
It only remains for me to wish you good reading and a good job.
