Best coaching assistance app

I have been coaching figure skating for 20+ years and skating has changed so much throughout the years. I’ve been looking for a program to help me better my coaching skills to better my skaters. This app has everything I could possibly need to make me a better coach for my skaters. If I have a question about rule I can go to this app to check. If I need to demonstrate a jump, spin or skating skill to my skater, I can open this app and show them a video. What a great teaching tool!! I can’t wait to use this daily in my lessons.
