Honest, I've tried to find the answer to this extremely-basic question in the FAQs and forum, but no luck:

I don't use either iPhone or iPod. I just use my MacBook, which goes everywhere I go. Am I correct that I can use iReal Book on my MacBook, but that I'll need to get the iReal Book Editor (Mac OS-X) in order to do that?

Thanks very much.
