Margins App Alternatives: 5 Book Trackers to Try in 2026

Most readers who outgrow Margins should look at StoryGraph first. It runs on the web as well as on phones, it has the detailed content warnings and book clubs Margins doesn’t advertise, and its mood filters cover some of the ground vibe search does. If typing a vibe was the part you loved and you want the next book chosen for you, Siftivo is built for that.

We should say up front that Siftivo is ours. Margins is a lovely app, with a 4.9 average from more than 19,000 US App Store ratings, and plenty of readers have no reason to leave it. Everything we say about the other apps is drawn from their sites and store listings, and Siftivo vs Margins compares the two in detail.

Margins is built for the feel of a book

Its whole design leans on atmosphere. You type “books like 1920s Paris” or “indie romantasy” and it hands back books with that feel, or you show it a Pinterest image and it finds books to match. Once you’re reading, it blocks social media and notifications, lets you pick the cover for your edition and turns your month into a hand-illustrated recap. For a reader who picks books by mood and wants reading to feel like a ritual, it’s hard to beat.

What its listings and site don’t describe is the other half of picking a book, which is knowing what you’re getting into. Margins doesn’t advertise content warnings, spice ratings, data export or library lending. Its vibe search matches a typed mood or an image, and the listings don’t describe it learning from books you abandon or dislike. As described, the search works from what you type tonight, and nothing in the listings says it rules out the kind of book you’ve given up on three times.

The other gaps are practical:

• It lives on your phone. The site says “Now on iOS and Android” and doesn’t advertise a web app for tracking.
• Kindle sync isn’t here yet. Margins rebuilt its app in September 2026 to prepare for it.
• The subscription is vague. Margins doesn’t publish what it unlocks beyond premium features and priority support.
• Social stops at following. You can follow readers and see what they read in Stories, but it doesn’t advertise clubs, buddy reads or forums.

Before you pick, decide whether you’re missing information about books, a way to rule books out, a bigger screen, or other readers. The apps below each answer one of those best.

1. StoryGraph

Best for

a full tracker on web and phone, with mood filters and content warnings

Price

Free, or Plus at $4.99/mo or $49.99/yr

Platforms

Web, iOS, Android

Visit StoryGraph

StoryGraph fills more of Margins’ gaps than any single app here. Its browse page combines 14 moods, three paces, fiction or nonfiction, genres to include or exclude, page-count bands and publication year, so you can narrow by feel with checkboxes. Content warnings come in two kinds, author-approved and reader-submitted, and the reader ones are graded Graphic, Moderate or Minor with vote counts. You can flag topics and content you’d rather avoid, and StoryGraph warns you on matching books and adjusts your recommendations. It runs on the web, iOS and Android, keeps quarter-star ratings, syncs Kobo progress automatically, and has book clubs, buddy reads and readalongs for up to 1,000 people. Its reading stats are the deepest of any mainstream book app.

The catch is that StoryGraph asks you to set filters where Margins lets you type a sentence or show it a picture. It doesn’t advertise a spice rating; sexual content shows up only as a content warning. It doesn’t advertise Kindle sync either, and its own roadmap lists offline mode on mobile as not yet built. Custom charts and extra stats filters sit in the paid Plus tier.

2. Siftivo (ours)

Best for

picks from three books you love, plus books to steer away from

Price

No paid plan

Platforms

Web, iOS

Visit Siftivo

Siftivo keeps the part of Margins where you type what you want in plain words, and adds a way to say what you don’t want. Search takes a description like “a slow, sad book about a lighthouse.” Beyond search, you start with three books you love and get three Daily Picks a day, and each pick and match badge names the book of yours behind it, The Night Circus for instance. Mark a book card Not for me and it stops coming back in Picks and Today, and the taste page holds up to three books to steer away from. One detail matters here. Passing on a book in Explore only removes that book, while a like does steer what comes next, so the taste page is where you steer away from a kind of book. It works on the web as well as on iPhone.

The catch is that Margins is the nicer daily tracker, and Siftivo is missing things Margins has. There’s no Android app, and the iPhone app has no iPad layout. Ratings stop at half stars where Margins now has quarters. There are no yearly goals or charts beyond a journal heatmap and profile counts, and you can’t export your data. Some book pages carry content warnings set by Siftivo’s catalog, but you can’t filter by them. If you love Margins as a place to read, keep it, and use Siftivo for the decision before you open the book.

3. Hardcover

Best for

content warnings, Filter Lists and an open API, ad-free

Price

Free, or Supporter at $4.99/mo or $49.99/yr

Platforms

Web, iOS, Android

Visit Hardcover

Hardcover is the answer if you want more control over what you see. Each book can carry genres, moods, tags and content warnings, and Filter Lists let you hide or label books and authors across the whole site, including filters other readers have made public. Its Vibes recommendations take a typed description too, and every logged-in reader gets the Discover page. It’s independent, ad-free, and on the web, iOS and Android, and its public API means your data isn’t stuck inside the app. Imports cover Goodreads, StoryGraph and a custom CSV.

Polish is where it trails. Its iOS app has 66 US ratings at a 4.2 average, against Margins’ thousands, and it’s listed in English only, where Margins comes in 14 languages. Creating your own Vibes, the personalized For You view and stats for any date range are Supporter-only. There’s no direct Kindle sync, and its book clubs were still in team alpha testing as of its October 2026 report.

4. Pagebound

Best for

per-book forums sorted by reading progress, with CSV export

Price

Free, or Pagebound Royalty at $10/mo or $100/yr

Platforms

Web, iOS, Android

Visit Pagebound

Pagebound is for the reader who wants Stories to turn into conversation. Instead of only seeing what someone is reading, you can talk to them about it on the book’s own forum, where you can sort posts by reading progress and spoiler tags keep anything past your page out of view. The feed is chronological and keeps spoiler posts for books on your TBR out by default. Ratings come in half stars with sub-ratings for enjoyment, quality, characters and plot, Quests turn reading into themed challenges with badges, and you can export your library to CSV. It runs on the web and both phone platforms, with no ads.

The catch is that Pagebound has no algorithmic recommendations at all, by design, so if vibe search was how you found books, nothing replaces it here. Discovery comes from forums, lists, Quests and readers’ suggestions on book pages. Its StoryGraph import is in beta, and per-read stats are part of the paid Royalty tier.

5. Romance.io

Best for

romance by steam level and more than 300 tropes

Price

Free; Supporter plan at $35/yr removes ads

Platforms

Web

Visit Romance.io

Margins’ own example searches include “indie romantasy” and “thriller with a love triangle,” and for readers who mostly search like that, Romance.io goes much deeper on the romance side. It covers more than 600,000 romance books on a five-level steam scale, from “glimpses and kisses” to “explicit and plentiful,” and lets you mix more than 300 content tags and tropes. Its find-similar search matches on tropes, themes, relationship dynamics and character types. It runs on the web and imports Goodreads, LibraryThing and StoryGraph exports.

It only does romance, though, and readers set the steam ratings, so some books won’t have one yet. It doesn’t advertise a mobile app, and we found none in a US App Store search, which is a big change after an app as good on a phone as Margins. Many of its retailer links are affiliate links. Use it beside a tracker, not instead of one.

My pick

StoryGraph is the trade most Margins readers should make. You give up typing a vibe and gain the web, content warnings and clubs.

Siftivo is for the reader whose favorite part was vibe search and who wants to tell the app what to stop showing. Hardcover goes further on filtering, hiding whole kinds of books or authors across the site.

For talking about what you’re reading, Pagebound. And if your searches were mostly romance, keep Margins for tracking and add Romance.io for choosing.

What I’d do today

1. Think of the last three books you gave up on and ask what you didn’t know before starting them. The answer tells you which gap matters.
2. If it was content, open StoryGraph on the web, set the topics you want to avoid, and check its warnings against those three books.
3. If it was taste, tell Siftivo the three books you love most at siftivo.com, mark the abandoned ones Not for me if they turn up, and see what tonight’s picks look like.
4. Keep Margins on your phone for the reading timer and blocker while you decide.
