I would use the crap out of this for my voice over work when I'm stuck in an isolation chamber and working alone. I just hope that it will also be on Windows and Android tablets. I've been looking to get a Surface Pro lately and would be kind of irked if it was only on iPads... which is kind of ironic when you consider that Sonar isn't Mac compatible (though yes, iPads are the popular tablet or something).
EDIT: From the looks of it, this isn't an official app, just someone who makes their own GUIs.
