BookSylo: Book Rank Tracker

Rank, rating and bestseller alerts for authors who sell on Amazon. Add your book once and BookSylo tells you when something changes, so you can stop refreshing the product page.

Built for self-published and indie authors on KDP, and for anyone who wants to follow a book's Best Sellers Rank (BSR), category ranks and ratings without watching Amazon all day.

No Amazon login. Ever. BookSylo reads public Amazon information only. It is not connected to your KDP account and never asks for your Amazon password. Sales and royalties stay in your KDP dashboard; BookSylo follows what readers see on the public book page.

WHAT BOOKSYLO WATCHES FOR YOUR BOOK
• Best Sellers Rank: the overall Amazon store rank, plus every category your book is listed in, with thresholds so small noise stays quiet.
• Category rank goals: set the Top N you are aiming for and see the goal line on your rank history graph.
• Bestseller milestones: an alert when your book breaks into a Top N, and a Best Seller signal in the Top 10.
• Rating alerts: the rating count goes up, or the star average moves.
• Price watch: public price changes for Kindle, paperback, hardcover and audiobook editions.
• Listing health: an alert when Amazon stops listing an edition, and again when it returns.

CAMPAIGNS FOR BOOK PROMOTIONS
Running a Kindle price drop, a newsletter or promo site feature, or an ad push? Start a Campaign for that window and see what changed in your book's public signals while it ran: typical rank before against typical rank during, the best position observed, and whether you reached the Top N you set, per book and per category. Finish with a result card you can share.

Every campaign says plainly what the numbers do and do not show: public observations, not sales, and no proof of what caused a change.

ALERTS ON YOUR TERMS
• The numbers are in the notification, for example "now at 48 ratings (+1)", not "something changed".
• Per-category control: each category can have its own threshold, or be muted.
• Daily summary: one digest a day if you prefer fewer notifications.
• Quiet hours, pause and snooze.
• Activity feed: every rank, rating, price, badge and milestone moment for a book in one list.

HOME-SCREEN WIDGET (Pro)
One book at a glance: rank, stars, ratings and price, with when it was last checked.

YOUR AUTHOR CATALOG AND ITS HISTORY
• Add a book by ASIN, ISBN, or title search with an optional author name.
• Kindle ebook, paperback, hardcover and audiobook editions across 22 Amazon marketplaces, including US, UK, Germany, France, Italy, Spain, Canada, Australia, Japan and India.
• Rank, rating and price history as graphs or a table.
• Private notes and labels: pin a note to the day a promo ran and see it on your graph.
• Track comp titles next to your own books (Pro).
• Share a rank snapshot or a finished campaign result. Only public metrics are shared.

WHY I BUILT IT
I am a self-published science fiction author. During my own launches I refreshed my book's Amazon page far too many times a day. BookSylo is the app I wanted: it looks for me and tells me when something actually changed.

Available in English, German and Spanish.
