ShotBook: Tennis Technique

ShotBook is a pocket reference for tennis technique. Every page breaks a technique into short steps, with simple illustrations and cautions. Search by name in English or Korean, and get back to pages you opened recently. Seven pages also list common mistakes and how to fix them. Everything is stored in the app, so it works without a connection.
