I don't see anywhere that discusses browser compatibility. If I can't use it on anything but bleeding edge browsers, it will be a long time before I can even think about something like this.
It should work on most recent browsers - but it will be much more performant on browsers that support web workers. If all of the calculations have to be done in the same main thread, it has no chance. Since it is targeting mobile apps, and all the mobile browsers can do web workers - that should be fine. Chrome and Firefox are fine back farther than it matters. But, IE9 and earlier will be slow because IE10 was the first IE to have web workers.
