BookSylo
Read full descriptionHide full description
Know the moment your book moves on Amazon. BookSylo watches your book's public Amazon pages and tells you when something meaningful changes — a rating, your rank, the price, or a bestseller badge — so you can stop refreshing and get back to writing. No Amazon login. Ever. BookSylo reads public Amazon information only. It is not connected to KDP, it is not a sales or revenue tracker, and it never asks for your Amazon password. WHAT BOOKSYLO WATCHES • Rating alerts — a new rating lands, or your star average shifts. • Rank movement — 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 history graph. • Milestones and badges — an alert when you break into a Top N, and a Best Seller signal in the Top 10. • Price watch — public price changes, alongside every other signal. • Listing health — an alert when Amazon stops listing an edition, and again when it returns. CAMPAIGNS Running a price drop, a newsletter feature, or an ad push? Start a Campaign for that window and see what changed in your book's public Amazon signals while it ran: typical rank before against typical rank during, the best position observed, and whether you reached a Top N you set — per book and per category, with the window marked on your graph. Finish with a result card you can share. Every campaign says plainly what the numbers do and don't show: public observations, not sales, and no proof of what caused a change. ALERTS ON YOUR TERMS • The numbers are in the notification — "now at 48 ratings (+1)", not "something changed". • Per-category control — each category can carry its own threshold, or be muted on its own. • Daily summaries — one digest a day if you would rather not be pinged. • Quiet hours, pause, and snooze. • Activity feed — every rating, rank, price, badge, and milestone moment for a book, in one list. HOME-SCREEN WIDGET One book at a glance — rank, stars, ratings, and price, with when it was last checked. Tap to open it. Choose any title or edition; it is then checked as often as BookSylo checks anything. (Pro) YOUR CATALOG AND ITS HISTORY • Add a book by ASIN, ISBN, or a title search with an optional author hint. • Kindle, paperback, hardcover, and audiobook editions across 22 Amazon marketplaces, from the US and UK to Japan, India, and Brazil. • Rating, rank, and price history as graphs or a table, with your notes marked on the graph. • Private notes and labels — pin a note to the day a promo ran and see it marked on your history. • Your most important books are checked most often; pin up to 3 into the fastest group. • Share a KPI snapshot, an Activity moment, or a finished campaign result — only public metrics, never your labels, notes, or email. PLANS Free — track 1 Amazon ASIN: one edition of one book in one marketplace. Full rating, rank, price, and badge tracking, notification controls, private labels and notes, one campaign at a time, to a shareable result, and 14 days of history. No account required. Pro — required to track 2 or more ASINs. Up to 50 ASINs across books, editions, formats, and marketplaces; multi-select from title search; edition grouping into one Home title card; the home-screen widget; comp title tracking; unlimited campaigns; Check now, once per hour per book and up to 20 a day; and 90 days of history. A 14-day free trial is available where offered. BookSylo Pro is an auto-renewing monthly subscription. It renews until cancelled, and you can cancel any time in your App Store account settings. Available in English, German, and Spanish. Works on iPhone and iPad. BookSylo is an independent product and is not affiliated with Amazon. A title only has data in a marketplace where it is actually listed.
