Invite-code/referrer system for Bookwise — the first social growth lever, framed as 'discover your reading friends' rather than community migration.

Authenticated server-side scraping of a user's Goodreads library on Bookwise sign-up — pipes shelves, ratings, reviews, and friends into TrackedBook so new users land in the app with their reading history already populated. The single most-used onboarding import path.

Self-serve Kindle library import on Bookwise sign-up — pulls a user's owned Kindle books, dedupes them against the Goodreads-imported library, and lands them on the Unsorted shelf. Pairs with the Goodreads-import path; the goal is to make Kindle take precedence on the open action while inheriting Goodreads metadata.

The sign-up screens themselves — email + password capture, profile setup (display name, username, photo), and the moment a new user is dropped from the social-network sandbox into the full app. The first thing every new Bookwise user touches.

The post-registration onboarding step sequence — what happens AFTER a new Bookwise user signs up but BEFORE they're free in the app. Covers the Welcome Carousel, Import Sources screen (Goodreads + Kindle), Find Friends, the staff-only first-reading-session step, and the home-page setup cards.
