StackBooks: Book Tracker & TBR

A reading tracker that makes adding books easy — and stacks up every book you finish.

ADDING A BOOK IS ONE SCAN

Point the camera at the barcode (ISBN) on the back of a book and the title, author, cover and page count are filled in.
Scans run back to back, so a whole bookshelf takes a couple of minutes.

You can also search by title or author and add a book from the results.

WHAT YOU READ BECOMES HEIGHT

The page count of each book turns into thickness, and your finished books pile up.
Look back on how tall your stack has grown.

A mug, an ostrich, a utility pole — your stack is drawn next to things you know, so you can see how far it has come.
You can also turn the stack into an image and share it.

YOUR TBR PILE AND YOUR READS, SORTED

Five statuses keep your books sorted: Wishlist, TBR, Reading, Read and Paused.
Books you're curious about go to Wishlist; books you own but haven't read yet go to TBR.
Move them to Reading when you start, Read when you finish, or Paused if you set them aside.

You can also see how tall your TBR pile alone has grown.

Finished books can hold a star rating, the date you finished, and a note about what you thought.
Add tags and you can filter later by "fiction", "work", or anything else you use.

RE-READS COUNT TOO

When you read a book again, each read gets its own finish date and notes.

EVERYTHING STAYS ON YOUR DEVICE

Titles, notes, ratings and the cover photos you take are kept on your device, not on a server.
There is no account and nothing to log in to.

When you change phones, export a backup and import it on the new one.

LOOK BACK ON YOUR READING

Built-in reading stats.
Books read, pages read and the height of your stack, whenever you want to see them.
See how much you read by author or by tag.
