TieCam Free includes 7 different knot types you can choose from: * Half Windsor * Four in Hand * Small Knot * Balthus * Plattsburgh * Saint Andrew * Kent Knot Tying instructions for additional knot types such as Windsor, Bow Tie or Pratt can be purchased from within the app as In-App purchase. You can control TieCam by speech recognition in order to have both hands free while tying the knot. If you are ready for the next sub-step, then just say 'next' and TieCam will proceed. Alternatively you can control TieSight manually by swiping horizontally over the tie image. For each knot type TieCam will show you a sequence of sub-steps which you have to imitate in your reflection.
