Self-published authors, rejoice!
Maybe I'm massively behind the times, but I just recently started using BookReport, and it has made my life so much easier.
You know how it gets confusing trying to read the Kindle sales board, especially now that we're trying to figure out pages read and all that mumbo-jumbo? BookReport does it for you. That's right - you just open your sales page, click on your BookReport bookmark, and you can see what you've made that day and that month.
You can try it free for two weeks. After that, it's $10 a month. Click here, and see what you think!
