This is must have service, it has everything you need to track for your KDP bossiness in one place. I like how the founder himself is there helping you to navigate through the platform if you'r lost in there. I highly recommend it.
By far the best tool for authors. EVER.
Great app - in use daily! I've never met a developer as open and responsive as Eiri. You suggest something, and it's there within minutes! He is constantly improving the app.
Great service. Responsive customer service, too. Wonderful product!
Publisher Champ is a fantastic platform and service. I see all my stats in one place which is indispensable in my business. I recently had a question and used the chat. I received a response in about 1 minute and was directly given the solution to my issue. Online customer service like I haven't dealt with in a long while. So nice. No AI, just a live person, right from the get-go.
I have been publishing on KDP for a long time, and I can't believe I had never tried this tool before. It is so helpful! It gives all the insights I need to see how much I am spending on ads per book, per day, and which are performing well and which are not. It is definitely worth it for any serious KDP publisher/author.
An incredible platform. I really don't know what I would do without it. With so many translations, and ads running, I would literally be at sea! Thoroughly recommend!
Powerful tool and prompt support!
AN Amazing tool !!!! Thank you!
By far the best monitoring report for authors in the business! Black Rose Writing uses the dashboard every day, and we have authors that have access to their own reporting, and they spend "way too much" time reviewing the data and loving Publisher Champ! There hasn't been anything even close in the past, and it's the best tool for publishers and authors in the world.
