Ive been using the site for months and months but only a few days however. Its great practice for me when Im at home. The only thing is I rarely feel like using my computer. I bought this app hoping for it to be similar to the site... Its actually better. The interface if super user friendly. It has a speed level, length level, it even keeps track of the fingerspelled words you get right. I am definitely, DEFINITELY going to use this daily. Thanks Dr. V
