This is one of the best investments I've made as an author. It is helping me master my ad spend. I can adjust my advertising campaigns on Amazon and see how my ROI improves in the coming days. The whole picture is easy to grasp: gross royalties, spending, net royalties for all your books or just one. The UI is so much easier than Amazon's. It's also great to have the journal feature to note when I made changes and see how they impact sales. And it lets me know when I sell a book! Fun!

Too expensive for what it is - considering you can access your kdp panel for free in a browser, this is a lot of money just to get notifications and very little else. It might be good for someone earning a lot of money, but for authors just starting out, it's prohibitively costly. Additionally, the price is not clear until you have created an account.

Hello Paul, our platform is not just for notifications. It has a lot more in depth statistics than Amazon itself so you can analyze your data with accuracy and in detail. Notifications are just 1 of our 25+ features. Either way, we wish you all the best.
Many thanks!

This app was pretty good until the developer got greedy. Some features used to be free while others required a paid subscription, but as of January 2024 they've taken away all the free features and are charging a ridiculously high amount per month. The subscription cost is actually more than a lot of KDP users earn per month by selling books. It's hard enough to make a profit without apps like this gouging you. You're better off checking your stats on your computer for free.

Hello there,
We are sorry that you feel that way. We have provided free features to all our users for 3+ years and unfortunately, with all the costs rising, we wanted to shift our focus to our subscribed users and provide a top-notch service.
We wish you every success on your KDP journey.
