I am missing the graph - so I can follow my progress more easily than now with only numbers.
Can you explain a bit more about what you mean?
I am guessing they mean the progress graph on the iPhone, which was replaced by numbers (but only for people using the coach - I think if you do not use the coach you have no numbers indicating how many points you earned at all?).
You explains it very well. I think the progress graph gives a momentum more than only numbers.
Another point would be the possibility to rehearsal the difficult words when you move around.
