Who is responsible for the user interface?
The idea and the expertise of the person behind this app really has potential, but seriously: the user interface is horrible, really horrible. Basic functionality like searching is a burden each time you use it, I mean hey - your customers pay for your service and we appreciate your technical expertise around Disklaviers. But please, get some help from people who know how to design an iOS App. This one looks and feels and works (not) like it was coded by a committee.
