Log your reading from a photo, not a keyboard. SHELVD is a book tracker that keeps up with how much you read, and keeps your Goodreads library and friends right where they are. FEATURES • Bookmark: Point your camera at any page or Kindle screen and SHELVD marks your place. It reads the page number and updates your progress in about two seconds. No typing. • Visual shelves: Your library lives as real, browsable shelves with spine art, not a list of rows. • Keep your Goodreads updated (Pro): Track everything in SHELVD and your Goodreads profile stays current on its own. Your progress, ratings, and finished books show up there automatically, so the friends you already have keep seeing what you're reading. No other reading app does this. • Bring your whole library: One upload imports your full Goodreads or StoryGraph history: ratings, read dates, and shelves included. • Reading stats: A heatmap of every day you've read, your reading pace, time-to-finish predictions, genre breakdowns, streaks, and progress toward your reading goals. • Book clubs: Read alongside friends, follow live progress on leaderboards, and share what you're into. Create and run your own clubs on Pro. • Snap a cover: Spot a book you want? Photograph the cover and SHELVD adds it to your want-to-read shelf (your TBR). • Hands-free Kindle tracking (Founders): Connect your Amazon account once and your Kindle reading logs itself, no photos needed. Your reading data stays yours. SHELVD never sells or shares your information with third parties. Terms of Use (EULA): https://shelvd.io/legal/terms Privacy Policy: https://shelvd.io/legal/privacy
