You're subscribed to five book boxes. Each one skips differently: one wants a form by the 5th, another an email by the 12th, a third won't let you skip at all this quarter. Miss one deadline and you've paid for a special edition you already own. Cratelog keeps it all straight: every subscription, every skip deadline, and every book you own in one place, built for special edition collectors. Keep StoryGraph or Goodreads for your reading; Cratelog tracks what they don't. NEVER MISS A SKIP DEADLINE Every box has its own skip window, limit, and way to skip. Cratelog knows them all. Get reminders 7, 3, or 1 day before each deadline, see how many skips you have left under each box's policy, and get a warning before a skip that could cancel your subscription or cost you early access. When it's time to act, Cratelog takes you to the right portal, email, or form, then records what you did so your counters stay accurate. DECIDE THE MONTH BEFORE IT CHARGES Every box with an open decision window sits on one screen: skip it, keep it, or sell it on. Filter to what you still have to decide, close a month in one tap, and when a box never ships a cycle, record that without spending a skip on it. PHOTOGRAPH YOUR OWN COPY Take seven shots of a book, jacket on and off; the app frames each face and finds the book by its edges. Turn the finished copy in 3D and look at the sprayed edges from any angle. Then stand your books on a shelf, spine out or edges out, in the order you arrange them yourself. If you have never photographed an edition, you see another reader's reviewed shots of it, credited. EVERY SUBSCRIPTION IN ONE PLACE One dashboard for all your boxes: renewal dates, next charge, skip counters, and a calendar of every billing day and deadline. Track waitlists for invite-only boxes and see how long others waited. Works with FairyLoot, Illumicrate, OwlCrate, Goldsboro, The Broken Binding, The Bookish Box, LitJoy, and dozens more through a community-maintained catalog. SEE WHAT'S COMING, SPOILER SAFE Theme and book reveals for your upcoming boxes, leaks and confirmed announcements clearly labeled, down to the sprayed edges, endpapers, and the artists behind them. Spoilers stay hidden until you choose to peek. YOUR COLLECTION, ON ONE SHELF Import your whole library from Goodreads or StoryGraph in one go, then scan a barcode for anything new. Signed, numbered, and sprayed edges badges, custom shelves, and series that show how many books you own and how many you have read. Cratelog warns you when a box book is already on your shelf, so you never buy the same edition twice. KNOW WHAT YOU SPEND (AND SAVE) Monthly and yearly spending across subscriptions and preorders, in your currency, plus a running total of the money skipping has saved you. PREORDERS, DROPS, AND SALES Track special edition preorders from any store, keep a wishlist of the ones you have not ordered yet, and follow a calendar of drops and warehouse sales in your local time, with an alert before a watched sale starts. CRATELOG PLUS, IF YOU WANT TO SUPPORT IT Everything above is free and stays free. Plus is an optional membership, monthly or annual, that helps cover what the app costs to run. It adds a Subscription Review of each box on the one to three measures you pick, from cost and skips to resale and edition design, and Compare, your boxes side by side on cost per month, cost per book, skips, ratings, and reading. Terms of Use: https://getcratelog.com/terms Privacy Policy: https://getcratelog.com/privacy THE HONEST PART Cratelog never skips, cancels, or buys anything for you; you act directly with the box company. Your collection is private, and deleting your account never touches your real subscriptions. Cratelog is an independent app made by one person, not affiliated with, sponsored by, or endorsed by any book box company. Brand names only describe which services you can track. Free to download and free to use. Never pay for a box you didn't want again.
