FAQ

How does ranking work?

There are no stars. When you finish a book, tabbd asks How was it?, and you answer Liked it, It was ok or Not for me. Then come a few duels: Which one stayed with you?, against books you already put in the same group. Each answer halves the range the book could land in, so it stays quick. With 10 books in the group you face at most 4 duels; with 100, at most 7.

• Too close to call puts the book just below the other one.
• Don't remember that one swaps in a different opponent.

Where do the scores come from?

From the book's place. Liked books score between 6.7 and 10, ok books between 3.4 and 6.6, and books that weren't for you between 0 and 3.3. Your favourite in a group sits at the top of its range. While a group holds fewer than ten books, scores stay closer to the middle, so your first liked book isn't an instant 10. Placing a new book can nudge its neighbours by a tenth or so. That's expected.

Can I change a book's place?

Yes, with Re-rank. It's on the book's page, in the score panel and in the … menu, and you can also long-press a book in Library → Top or Read. The book keeps its old place until you finish the duels, so cancelling is safe. Afterwards you'll see how far it moved.

What are cards and the player card?

Every finished read prints a collectible card: Common, Rare, Holo or Legendary, with stamps for how you read it. A card is printed once and never re-rolls.

The player card sums you up as a reader. It has an overall rating, six stats (PACE, DAYS, DEEP, RANGE, NOTES, DONE), a tier from Bronze to Icon, and an archetype. It calibrates over your first week, then updates every Monday. It's just for fun: it unlocks nothing.

Who sees my scores?

Only your friends, and only if you allow it. Tap your photo, then the gear icon, then Privacy, and turn off Show scores as numbers: friends will then see a place and a word, not the number. Each book's community score is an anonymous average of everyone's scores.

How do I make my profile private?

Go to Privacy (photo → gear) and set Who sees your profile to Only me. Friends then see only your name and photo; in a co-reading you joined, its members still see your messages and how far you are in that book. Diary entries stay private unless you open one to friends, and page photos are always private.

How do I add a friend?

Open Friends and tap +. Type their exact @username, or scan the QR code on their phone (yours is on the same screen). They accept, and you're friends. Nobody can search for you by name.

How do I remove or block someone?

Open their page, tap …, then choose Remove friend or Block. Blocking ends the friendship, and they can no longer find you or send requests. You can also decline any request. You can't unblock someone in the app yet; email us and we'll do it.

How do I delete my account?

Tap your photo at the top of Home, Library or Friends. Then tap the gear icon, go to Account → Delete account, and confirm. It can't be undone. Sign out is different: it keeps your account. If some changes haven't reached our server yet, tabbd warns you before you sign out. See the Privacy Policy for what deletion removes.

Can I export my data?

Not in the app yet; it's on our list. Email gettabbd@gmail.com and we'll send you a copy within 30 days.
