Endleaf VS Readlink

Endleaf's answer

The whole tracker is free. Unlimited books and reading sessions, half and quarter star ratings, six statuses, the reading timer, Goodreads and StoryGraph import, and full JSON and CSV export all work without paying and without an account. The library lives on the device and syncs through the reader's own iCloud, so no server of ours ever holds it. Ratings carry optional sub-ratings for plot, characters, quality and enjoyment. Audiobooks are logged in hours and minutes with their own progress bar instead of invented page counts, and approximate dates let someone record a book they finished sometime in 2019.

Readlink's answer:

Readlink is the all-in-one book app. Instead of one app to track, another to read, another for notes and a group chat to talk about it, Readlink does all of it: book search and barcode scan, one-tap page tracking, a PDF reader with highlights and notes, reading stats and streaks, author pages, and a social feed where every post is tied to a real book. It also compares your library with other readers and with curated libraries of founders, writers and thinkers, and shows exactly which books you share.

Endleaf's answer

Goodreads has no half stars and drops start dates when you export. Bookly puts its reading timer behind a subscription. Endleaf gives half and quarter stars, a timer that runs on the lock screen and in the Dynamic Island, Apple Watch logging, and a full JSON or CSV export on the free tier. There are no ads, no trackers and no feed to scroll. The only request that leaves the device is a title or ISBN sent to look up a cover, and nothing about the reader is stored.

Readlink's answer:

Most book apps do one job. Goodreads and StoryGraph track, e-readers read, note apps hold highlights, and the conversation happens somewhere else. Readlink keeps the whole reading life in one place, so your progress, notes and discussions stay attached to the book. Recommendations come from the books you actually finished, not just what you added. Moving is easy: import your Goodreads shelves from a profile link or CSV. The core app is free, and Premium adds AI reading chats across your own books and notes, plus shelf scanning that adds a whole bookshelf from one photo.

Endleaf's answer

Readers who keep track of their own reading and want that record private. A lot of them are moving off Goodreads or StoryGraph and bring a CSV with them. They log sessions, set a yearly goal, rate in half stars, and keep quotes and notes per book. Endleaf is built for iPhone, iPad and Apple Watch, needs no account, and works with no connection.

Readlink's answer:

Curious readers who read to learn, mainly non-fiction: founders, builders, researchers, students and anyone whose reading shapes how they work and think. They want a clean record of what they read, a place to keep the ideas that stayed with them, and other serious readers to talk to. Fiction readers are welcome too, and can shelve anything.

Endleaf's answer

The iPhone, iPad and Apple Watch apps are written in Swift with SwiftUI. Books and sessions are stored on the device with SwiftData and synced through the reader's own iCloud using CloudKit, so no server of ours holds a library. WidgetKit powers the home and lock screen widgets, ActivityKit runs the reading timer's Live Activity, and StoreKit handles the premium purchase. The website is a static Astro site styled with Tailwind CSS.

Readlink's answer:

React Native with Expo for the iOS and Android apps, TypeScript throughout, a Node.js API on Fastify with Prisma and PostgreSQL, Upstash Redis for caching, Clerk for authentication, Next.js on Vercel for the website, Cloudflare R2 for images, Google Gemini for AI features, RevenueCat and Stripe for subscriptions, and PostHog for product analytics.

Readlink's answer:

Readlink is developed by Lykan Sagl in Switzerland together with Quanteron in the USA, and launched on iOS and Android in June 2026. The mission is to change how readers organize, manage and share their personal libraries and the knowledge in them. Since launch it has grown from a library and social feed into a full book app, adding a reading tracker and stats, a PDF reader, author pages, weekly picks, AI reading chats and AI shelf scanning.
