Great structure to the app, etchings are good, yet the free pour art pictures and videos lack precision and attention to detail. Examples are often asymmetrical and not centered in the cup. The shown pouring technique also lacks smoothness. The demonstrator is very jerky with the pitcher, forcing the push to appear. These factors all figure into pleasant presentation. Of course, nobody will pour perfectly every time, yet for video demonstrations and tutorials I would think it ideal to show users the best that can be done, a certain level of quality for somebody to strive to achieve.
