Build the bookshelf you've always wanted — then actually read the books on it. SlowRead turns reading into a slow, intentional ritual: a gorgeous 2.5D bookshelf you'll be proud to show off, focus sessions that really block the apps stealing your attention, and a reading streak that keeps you coming back. — A BOOKSHELF WORTH SHOWING OFF — Every book you add becomes a beautiful spine or cover on a warm, hand-illustrated shelf. Photograph a real book spine to bring its exact look into your library, rearrange your books by dragging them around, and decorate your shelves with plants, candles, clocks and more. Switch between a cozy Cottagecore light theme and a moody Dark Academia dark theme. It's a bookshelf that finally feels like yours — made for booktok and romantasy lovers. — FOCUS SESSIONS THAT ACTUALLY BLOCK DISTRACTIONS — This is what makes SlowRead different. Start a timed reading session and SlowRead really blocks your distracting apps — not a gentle reminder, an actual block powered by Screen Time. Close Instagram, open your book, and stay there. Your session keeps going even if you leave the app or your phone restarts, so there's no cheating your way back to the feed. — BUILD A READING STREAK YOU'RE PROUD OF — Set a simple daily reading goal in minutes and watch your streak grow on a beautiful calendar and heatmap. A fresh literary quote greets you each day. Small, gentle nudges — never guilt. — TRACK EVERY BOOK, EFFORTLESSLY — Organize your TBR, currently reading and finished books. Create custom libraries for any collection — series, moods, seasons — and tag books however you think. Add private notes, log rereads, and track your start and finish dates. Everything stays neat, searchable and yours. — ADD BOOKS IN SECONDS — Search millions of titles across multiple book databases, scan a barcode, or snap a photo of a spine. Covers are fetched automatically so your shelf looks stunning from the very first book. — BRING YOUR LIBRARY WITH YOU — Coming from Goodreads? Import your entire library from a CSV export in a few taps, and SlowRead backfills the missing covers for you. — PRIVATE BY DESIGN — SlowRead is local-first. Your library lives on your device, not on our servers. No feed, no ads, no noise — just you and your books. Start your first slow reading session today. Your shelf, and your attention span, will thank you. All features described above require a subscription. A free trial is included, so you can try everything before paying.
