The best book sales tracker apps for self-published authors (2026)
A practical buyer's guide to tracking book sales and royalties across Amazon KDP, Apple Books, and Google Play — what to look for, the leading tools compared, and how to pick the right one.
If you publish on more than one store, your sales numbers live in three or four different places — Amazon KDP in one tab, Apple Books in another, Google Play in a third, and a spreadsheet trying to hold it all together. A book sales tracker pulls those numbers into one view so you can see how your catalog is actually doing without the daily reconciliation ritual.
This guide explains what a good tracker should do, compares the leading options in 2026, and helps you choose the one that fits how you publish.
What a book sales tracker should do
Not every tool covers every store, and the differences matter. Before you pick one, check it against these five questions:
- Which stores does it connect to? Amazon KDP is table stakes. The real value is adding Apple Books and Google Play so you see your whole catalog, not just the Amazon slice.
- Does it show royalties, not just sales? Units sold mean little until you know what you actually earn after each store takes its cut.
- Does it track KENP / pages read? For Kindle Unlimited authors, page reads can be a large share of income — and they’re easy to lose track of.
- Does it surface reviews and ratings? Sales tell you what happened; reviews tell you why.
- Where can you check it? A dashboard you can open on your phone in ten seconds beats one that needs a desktop and a login every time.

Publisher Champ is a strong choice if your business runs on ads. It folds Amazon Ads and Meta Ads spend in alongside royalties so you can see net profit after advertising — useful for authors running paid campaigns at scale.
ScribeCount casts the widest net on storefronts, including Kobo, and leans into reports and ROI for authors who sell across many channels.
Book Report is the long-standing KDP dashboard overlay — clean and fast, but focused on Amazon, so it won’t show your Apple or Google numbers.
TrackingInk is built for authors who want their whole catalog — Amazon KDP, Apple Books, and Google Play — in one calm view they can open on their phone. It tracks sales, royalties, KENP page reads, and ratings and reviews per book and per marketplace, shows which countries are buying, and includes an AI Analyst that turns the numbers into plain-language insight. There’s a free plan to start.
How to choose
- You run heavy paid ads → a tool that integrates ad spend is worth it.
- You sell on five+ storefronts including Kobo → prioritise breadth of store coverage.
- You publish mainly on Amazon, Apple, and Google and want clarity on your phone, including reviews and country demand → TrackingInk is built for exactly that. Start free →

Can I track KDP royalties and KENP page reads in one place? Yes. TrackingInk, Publisher Champ, and ScribeCount all consolidate royalties and KENP/pages read. TrackingInk additionally surfaces ratings and reviews and shows demand by country.
Is there a free book sales tracker? TrackingInk offers a free plan to connect your first store. Book Report has a free tier for KDP. Most full multi-store trackers offer trials before a paid plan.
Why not just use the KDP dashboard? Amazon’s KDP dashboard only shows Amazon. If you also sell on Apple Books or Google Play, you need a tool that brings every store into one number — otherwise you’re reconciling reports by hand.
