I was one of the testers for the app, after the Smooth Move was recommended for a shoulder pain that had persisted for a few months with no sign of improving. The pain gradually reduced to a 75% improvement over 3 months and now is such that there isn't really any discomfort when I move my shoulder. The app is easy enough to use, though when I got so good at moving smoothly that my rating was 100 out of 100, my husband needed to help adjust the ratings so I have a new target to aim for. Even without a shoulder pain to reduce I continue using the app as it is quite fun to practice and keep away any new aches.
I have been one of the testers for over a year now, during the development of the app. Before starting with Smooth Move I had been getting increasing amounts of hand tremors, and it had got to the point where I could no longer carry drinks for fear of spilling them. After a few months of using Smooth Move for a 7 minutes practice daily, I was increasingly able to bring the tremors under control. After 6 months or so I could start to carry drinks again, and within a year have the confidence to carry a cup of coffee across carpets around the house. My family now tell me the tremors are barely noticeable. It certainly seems to have worked for me, and would be happy to recommend anyone else to try it for similar hand tremor conditions. The daily practice is just 7 minutes, of simple exercises, from the video included with the app. Being naturally competitive, the challenge of bettering my previous score and getting an improving trend keeps me doing this daily exercise.
