The 7 Best Book Tracker Apps in 2026

An honest comparison from someone who built one.

I’m the creator of Shellf, a book tracking app with AI-powered recommendations. That means I have an obvious bias — and I’m going to be upfront about it. I’ve spent months researching every competitor, reading thousands of Reddit threads, app reviews, and community posts. I’ve used most of these apps myself. What follows is the most honest comparison I can write, including an unflinching look at where Shellf falls short.

Goodreads

The one everyone starts with

Free

iOS, Android, Web

150M+ readers

Let’s start with the elephant in the room. Goodreads has 150 million users, the largest book database on the planet, and it’s completely free. If you want to know whether a book exists, Goodreads almost certainly has it. If you want to read a hundred reviews before you commit, Goodreads has those too.

But here’s what I’ve found after years of using it: Goodreads is coasting. Amazon bought it in 2013 and meaningful development essentially stopped. The interface still feels like 2011. They finally updated their logo in mid-2025 — their first-ever logo redesign, after nearly 20 years — but skipped the features readers have been begging for. Still no half-star ratings. Still no proper dark mode. The “Did Not Finish” shelf only became a native feature in March 2026.

I see on Reddit and app reviews that the biggest frustration is the recommendations. Goodreads has more reading data than any app on earth and consistently wastes it. Their suggestions skew toward whatever is currently popular or whatever Amazon is selling — not what would actually resonate with your taste.

The community is a double-edged sword. It’s massive, which means you’ll find discussion on virtually any book. But review bombing, author harassment, and weak moderation have become real problems. The Android app has well-documented issues where reviews and friend activity appear frozen months or years behind.

There’s another angle that doesn’t get discussed enough: Amazon integration. If you buy books on Amazon — especially Kindle books — Goodreads is seamlessly woven into that ecosystem. Your purchases appear in your feed, Kindle highlights sync, and the whole pipeline from “discover a book” to “buy it in one tap” is frictionless. For readers who don’t take tracking too seriously and just want a lightweight companion to their Kindle, Goodreads is genuinely hard to beat. That integration is Amazon’s real competitive moat — not the features, not the community.

The reason I think Goodreads persists isn’t because it’s good — it’s because the switching cost feels enormous. You’ve got years of data in there, a friends list, shelves you’ve carefully curated, and if you’re a Kindle reader, a purchase history that no other app can touch. That lock-in is the real product.

Pros

  • Largest book database and community by far
  • Completely free with no paywalled features
  • Deep Amazon/Kindle integration — seamless purchase-to-tracking pipeline
  • Extensive reviews and ratings for virtually every book
  • Reading challenges with community participation
  • Universal — most readers already have an account

Cons

  • Stagnant development — no meaningful feature updates in years
  • No half-star ratings (a long-standing position)
  • No dark mode on iOS or desktop
  • Recommendation quality is poor despite massive data
  • Amazon ownership concerns for privacy-conscious readers
  • Review bombing and weak community moderation

Best for

Readers who want the largest community and most comprehensive book database. If community reviews matter more to you than analytics or recommendations, nothing comes close.

Weakest at

Recommendations, modern UX, and respecting power users' data. Goodreads treats your reading history as Amazon purchase data, not taste intelligence.

The StoryGraph

The indie darling that proved Goodreads could be challenged

Free / Plus $49.99/yr

iOS, Android, Web

adventurousdarkemotionalfunnyhopeful
4.25

I have enormous respect for what Nadia Odunayo has built with StoryGraph. A tiny indie team reaching 5 million signups and winning an Apple App Store Award in 2025 is genuinely remarkable. It proved that readers will leave Goodreads if you give them something better.

And in many ways, StoryGraph is better. The reading stats are the real draw — mood tracking, pace analysis, genre breakdowns, and a year-in-review wrap-up that readers love to share. The quarter-star rating system (0.25 increments) is a small thing that matters a lot when you’re trying to distinguish between a 3.5 and a 4. Crowdsourced content warnings are genuinely useful. DNF tracking that doesn’t tank your stats was a revelation.

When I researched StoryGraph’s weaknesses, two things stood out. First, social features are deliberately minimal — you couldn’t even like a review until February 2026, and commenting on reviews still isn’t possible. I see on Reddit that this is the number one reason people keep Goodreads alongside StoryGraph — the community conversation just isn’t there.

Second, the recommendations. StoryGraph uses a neural network trained on mood, theme, and genre data. They’re decent — better than Goodreads — but users report they’re not mind-blowing. The AI-generated book descriptions have been controversial, with users actively complaining about seeing AI summaries instead of publisher descriptions. The mood and pacing data is auto-generated and frequently inaccurate.

The price is the other sticking point. $49.99/year is steep for a book tracking app. The Plus features — mostly advanced stats filters and custom graphs — are nice-to-haves, not must-haves. I see many users explicitly say they don’t see the value at that price. That said, the free tier is genuinely generous and enough for most readers.

I should be honest about something: a lot of people seem to think StoryGraph’s UX is good, and I understand why — it’s certainly cleaner than Goodreads. But one of the reasons I started building Shellf in the first place is that I found StoryGraph’s interface unintuitive and cluttered in its own way, and so did friends I showed it to. The navigation can feel buried, the settings are sprawling, and the mobile app doesn’t always feel native. That’s a subjective take — clearly millions of people disagree — but it was a genuine motivation for me.

Pros

  • Best-in-class reading stats and data visualisation
  • Quarter-star ratings (0.25 increments)
  • Crowdsourced content warnings by severity
  • DNF tracking that doesn't penalise your stats
  • Generous free tier covers most needs
  • Not Amazon-owned — important to many readers
  • Clean, modern interface
  • Seamless Goodreads import

Cons

  • Social features are minimal — no review comments, limited interaction
  • Plus subscription at $49.99/year is expensive for what you get
  • Auto-generated mood/pacing data is frequently wrong
  • AI-generated descriptions are controversial
  • Performance issues and occasional outages (small team, large user base)
  • Book sorting and organisation is limited — no secondary sort, no cover view

Best for

Readers who care about understanding their reading patterns. If stats, mood tracking, and clean analytics are your thing, StoryGraph is the best in the market.

Weakest at

Social features and community. If you want to discuss books with friends or discover through conversation, you'll still need Goodreads alongside it.

Fable is the odd one out on this list because it’s not really a book tracker — it’s a book club platform that also happens to track books. That distinction matters.

With over 100,000 active book clubs led by authors, BookTokkers, celebrities, and readers, Fable has carved out a genuine niche. If you want to join a structured book club without managing a group chat, Fable does this better than anyone. The annotation features — highlighting passages, commenting, seeing others’ perspectives in-text — are genuinely clever. The “Folios” (curated recommendation lists from tastemakers) are a nice discovery mechanic.

In mid-2025, Fable was acquired by Everand (a Scribd company). Both apps continue to operate, but the long-term direction is worth watching. Everand brings a massive catalog of ebooks and audiobooks, which could make Fable a compelling all-in-one reading platform — or it could pull focus away from what made Fable special.

The reason I think Fable works for some readers and not others is the book club focus itself. If you’re not a book club person, most of Fable’s best features are irrelevant to you. The basic tracking and goal-setting features exist but aren’t as deep as dedicated trackers. The premium price at $69.99/year is the highest on this list, and it’s primarily paying for access to premium book clubs, not tracking features.

I also found that Fable’s own 2025 State of Reading Report revealed that human recommendations still outperform algorithms for their users — which is interesting positioning for an app that doesn’t invest heavily in AI recommendations.

The honest truth: Fable is the competitor I respect most. They found a specific thing readers actually want — structured book clubs without the overhead — and built it beautifully. They didn’t try to be everything. That focus is something I’ve learned from.

Pros

  • Best book club platform — 100,000+ active clubs
  • In-text annotations and shared highlights
  • Folio curations from tastemakers and authors
  • Daily streaks and reading goals for motivation
  • Backed by Everand/Scribd — stable funding and catalog access

Cons

  • Most expensive option at $69.99/year for premium
  • Tracking features are secondary to the book club experience
  • No AI-powered recommendations
  • Everand acquisition raises questions about long-term direction
  • Limited reading stats compared to StoryGraph or Bookly
  • No DNF tracking

Best for

Social readers who want structured book club experiences. If joining clubs led by authors and BookTok creators sounds like your ideal reading life, Fable is unmatched.

Weakest at

Solo readers who want analytics-driven tracking. If you read independently and want deep stats or AI recommendations, Fable isn't built for you.

Bookly

The reading timer that gamifies your habit

Free / Pro $29.99/yr

iOS, Android

5-day streak

Bookly answers a very specific question: “How do I read more?” If your goal is building a daily reading habit, Bookly is arguably the best tool for the job.

The core mechanic is a reading timer. You start a session, read, stop the timer, log your pages. Bookly then calculates your reading speed, predicts when you’ll finish the book, and tracks your progress against daily, monthly, and yearly goals. It even offers ambient sounds — rain, café noise, fireplace — to help you focus. It’s genuinely well-designed for habit formation.

Recent additions include a “Book Characters” feature for tracking character relationships (useful for epic fantasy readers), and a chat interface with Bloo — Bookly’s long-standing reading assistant mascot — that now offers conversational book discussion and personalised recommendations. Neither feature is deep, but they show the team is actively developing.

The catch with Bookly is the paywall. The free version is restrictive — many core features sit behind the Pro subscription. At $29.99/year it’s reasonably priced, but the free experience can feel like a demo.

The reason I think Bookly and Shellf serve different readers is fundamental: Bookly helps you read more, Shellf helps you discover what to read. If you already know what you want to read and just need accountability, Bookly is excellent. If your problem is finding books that match your taste, it won’t help much.

Pros

  • Best reading timer with speed calculation and finish predictions
  • Daily/monthly/yearly goal tracking with streaks
  • Ambient sounds for focused reading sessions
  • Clean, motivating UI designed for habit building
  • Detailed per-session reading statistics
  • Barcode scanner for quick book adds

Cons

  • Free version is heavily restricted
  • No social features whatsoever — solo experience only
  • No web app — mobile only
  • Recommendation quality is basic (AI chatbot, not personalised)
  • Book discovery isn't the focus
  • No Goodreads import on free tier

Best for

Readers who struggle with consistency and want to build a daily reading habit. The timer-based approach with ambient sounds and streak tracking is uniquely motivating.

Weakest at

Book discovery and social reading. If you need recommendations or community, look elsewhere.

Litsy

Instagram for book lovers

Free

iOS, Android, Web

Just finished and I'm devastated in the best way...

"We are all in the gutter, but some of us are looking at the stars."

blurbquotereview

Litsy is the closest thing to a “bookish Instagram” that exists. It’s a social platform first, tracker second. You post blurbs (300 characters max), share quotes, write short reviews, and upload photos of books alongside your thoughts. Every post is tied to a book, which keeps the feed focused.

What I’ve found charming about Litsy is the community. It’s small, warm, and noticeably less toxic than Goodreads. The “Litfluence” score gamifies engagement, readathons bring people together, and the visual format makes scrolling through the feed genuinely enjoyable. Librarians, booksellers, and authors are active alongside regular readers.

Now for the honest part: Litsy is niche and staying niche. It was acquired by LibraryThing in 2018, which gave it stability but limited ambition. Development is slow. There are no reading stats to speak of, no reading goals, no AI recommendations, and no barcode scanner. The tracking features are basic — you can add books to a “stack” (their term for a shelf) and that’s about it.

The reason I think Litsy has lasted despite these limitations is that it does one thing well: it makes sharing about books feel natural and visual. If you’re a Bookstagram creator who wants a dedicated app for book-centric social posting, Litsy fills that gap. But if you want a tracker with depth, it’s not the right tool.

Pros

  • Warm, non-toxic community of engaged readers
  • Visual, Instagram-like format for sharing book thoughts
  • Completely free with no paywalled features
  • Active author and librarian participation
  • Web app alongside mobile

Cons

  • No reading stats, goals, or analytics
  • No AI recommendations or discovery features
  • No barcode scanner
  • Slow development pace under LibraryThing ownership
  • Small user base limits discovery potential
  • 300-character post limit is restrictive for deeper reviews
  • No Goodreads import

Best for

Readers who want a cosy, visual social experience focused on books. If you love Bookstagram culture and want a dedicated space for short-form book thoughts, Litsy nails it.

Weakest at

Everything except social. No stats, no recommendations, no goals, no serious tracking. It's a social app that happens to involve books, not a book tracker with social features.

Leio is one of those apps that doesn’t get much attention in comparison articles, which is a shame because it does a few things very well. The design is clean and modern — users consistently praise the UI as feeling thoughtful and uncluttered. The reading timer with session tracking, finish-date predictions, and deadline setting is well-executed.

I see on app reviews that what sets Leio apart is the “achievements” system — it makes tracking feel like a game, which is surprisingly motivating. The barcode scanner works well, and the quote-saving feature is appreciated. You can track progress across multiple books simultaneously and export your reading data for analysis.

The problem is the free tier. You can only track one book at a time without paying, which for any reader who juggles multiple books, makes the free version essentially unusable. Users also report data loss issues and lack of cross-device sync, which is concerning for a tool that’s meant to hold your reading history.

When I researched Leio’s user base, it’s clearly smaller than the others on this list. There’s no web app, no social features, and no AI recommendations. It’s a focused reading timer with good design — similar territory to Bookly but with a smaller team and less polish overall.

Pros

  • Clean, modern design that doesn't feel cluttered
  • Reading timer with session tracking and finish predictions
  • Achievement system adds gamification
  • Quote saving and note organisation
  • Barcode scanner for adding books
  • Reading data export

Cons

  • Free tier limited to one book — essentially unusable
  • Reports of data loss and sync issues
  • No cross-device sync
  • No web app
  • No social features or community
  • No AI recommendations
  • No Goodreads import
  • Small team and user base

Best for

Readers who want a clean, gamified reading timer and don't mind paying for it. If Bookly feels too busy and you prefer minimalism, Leio might be your speed.

Weakest at

Reliability and the free tier. The one-book free limit is punishing, and data loss reports are a red flag for a tool holding your reading history.

Shellf

The one I built — here's the honest version

Free / Plus $18/yr

Android (iOS mid-2026)

Recommended for you

“Because you loved the unreliable narrators in...”

Your library

Right. This is the part where I have to be honest about my own app, and I’m going to try harder here than anywhere else on this page.

Shellf’s core idea is simple: what if a book tracker actually learned your taste? Not your genres — your taste. The themes you gravitate toward, the narrative styles that resonate, the connections between your favourite books that you might not consciously see. I built an AI recommendation system using embeddings (essentially mapping every book into a high-dimensional taste space) combined with LLM-powered reasoning. The more books you rate, the sharper it gets.

I’ve found that readers with 30+ rated books start getting recommendations that genuinely surprise them — not “popular books in your genre” but specific titles they’d never have found, with explanations for why they might connect. That’s the part I’m most proud of.

The reading stats are different from StoryGraph’s, but I think they’re on a par. You get books read, pages read, monthly trends, genre breakdowns, fiction vs non-fiction splits, and a taste fingerprint showing what themes and qualities you tend to love. We don’t do mood or pace tracking the way StoryGraph does, but Shellf Plus uses AI to generate reader insights based on the books you’ve actually read — connections between your favourites, patterns in what resonates with you, and why. I think that’s pretty neat, and the feedback has been very positive.

Organisation is genuinely strong. Custom shelves built from tag rules (any/all matching), DNF tracking with reasons, half-star ratings, notes with voice dictation, and a visual bookshelf metaphor instead of flat lists. Import from Goodreads (direct OAuth, not just CSV), StoryGraph export files, or any spreadsheet. Barcode scanner for physical books.

Now, the honest gaps:

  • iOS isn’t out yet. It’s in development and coming soon, but right now Shellf is Android-only. For a lot of readers, that’s a dealbreaker. I know.
  • No web app. You can import your library via the website and manage your account, but the current experience is app only.
  • Social features aren’t a focus — for now. It’s not that we’ll never do social, but right now I’m focused on helping voracious readers understand themselves through insights and get great recommendations for their next book. No public profiles, no followers, no social feed. That might change, but it’s not where the energy is going today.
  • No reading timer. Habit-forming isn’t our focus. If you need a timer to motivate your reading sessions, Bookly does it better.
  • No content warnings. StoryGraph’s crowdsourced content warning system is genuinely useful and we don’t have anything equivalent. That’s on the roadmap, but I won’t pretend it’s close.
  • We’re young. Shellf launched in 2026. Our user base is small, our book database is growing but not yet at Goodreads or StoryGraph scale, and there are features that larger teams have had years to build. What we do have is speed — as a solo creator, I ship fast and respond to feedback immediately.

The pricing is where I feel confident. At $18/year for Shellf Plus, it’s 64% cheaper than StoryGraph Plus and 74% cheaper than Fable Premium. The free tier includes unlimited book tracking, full library organisation, reading stats, and 100 AI recommendation credits — enough for months of discovery. No time limit, no credit card required.

The reason I built Shellf is actually down to my wife. She’s a power reader who gets through well over 50 books a year. She can’t get quality recommendations from any of the apps she’s used. She can’t get the level of introspection from stats and analytics that she wants from other apps. I’m a moderate reader, but she is my target market — and Shellf is the app I wish existed for her. We’re not there yet on every dimension, but the recommendation engine is genuinely good, and it gets better with every book you rate.

Pros

  • AI recommendations that genuinely learn your taste (embeddings + LLM)
  • Cheapest premium tier at $18/year
  • Generous free plan — unlimited tracking + 100 AI credits
  • Clean, dark-first design with bookshelf visual metaphor
  • Strong organisation — custom shelves, tags, DNF tracking with reasons
  • Half-star ratings and voice-dictated notes
  • Import from Goodreads (OAuth), StoryGraph, and CSV
  • Barcode scanner for physical books
  • Private by design — no social feed, no public profiles
  • Solo creator = fast iteration and direct feedback loop

Cons

  • Android only right now — iOS mid-2026
  • No web app for reading/browsing
  • Social features aren't a focus yet
  • No reading timer or habit-building tools
  • No content warnings
  • Young app — smaller database and community

Best for

Power readers (30+ books/year) who are frustrated with generic recommendations. If your problem is 'I've read everything obvious in my genres and can't find what to read next,' Shellf's AI is built for exactly that.

Weakest at

Platform availability and social. Until iOS ships, we're excluding half the market. And if community discussion matters to you, we're not the app — by design.
