Siftivo vs Margins: Vibe Search or Three-Book Picks? (2026)

Margins and Siftivo are both trying to get you to a good book, and they go about it in different ways. Margins is a beautifully designed reading tracker for iPhone and Android, with vibe search that finds books from a typed mood or even a photo, and a blocker that shuts off other apps while you read. Siftivo picks your next book from three books you love, on the web and iPhone, and doesn’t need you to describe anything. We’re the people behind Siftivo, so factor that in. The facts about Margins here come from its App Store and Google Play listings and its own site.

Pick Margins if you know the feeling you want, or you need help actually reading. If you can type “thriller with a love triangle” and mean it, care how your shelf looks, read on Android, or keep losing your reading time to your phone, Margins does all of that well.

Pick Siftivo if you can’t name what you want next. If you’d rather the app bring you three books a day based on the books you already love, or you want to use it from a laptop, Siftivo is the closer fit.

Two reasons a book goes unfinished

Some books go unfinished because they were the wrong book. You picked on a cover or a recommendation that didn’t fit you, and by chapter six you’re reading out of duty. Others go unfinished because you never sat down with them. The book was fine, but the phone was right there, and a week later you’ve lost the thread. If you want to see the first kind up close, our post on the most abandoned books on Goodreads marks the stretch where readers give up on each of ten.

Margins has a real answer to the second problem. Its blocker turns off social media, notifications and other apps while you read, with a reading timer and rain sounds, and when the session ends it asks how far you got. Siftivo works on the first problem instead, getting the right book in your hands before you start.

Searching by mood, and when you don’t have one

Margins’ vibe search is very good, and it’s the strongest mood-first discovery of the apps we compared. Type a mood, a plot, a setting or a vibe, like “books like 1920s Paris” or “indie romantasy”, and books come back. You can even turn a Pinterest image or a photo from your camera roll into recommendations, which is a lovely idea for readers who think in pictures.

Siftivo’s search takes a plain description too, so on the nights you know what you want, the two apps are closer than they look. The difference shows on the other nights. Margins’ listings describe vibe search as matching what you type or the image you give it, and they don’t describe learning from books you abandon or dislike. Siftivo starts from your favorites and has picks waiting before you ask.

How Siftivo picks for you

When you sign up, Siftivo asks for three books you love, and those three drive everything after. Daily Picks hands you three books each day, each naming the book of yours that led to it, and a match badge on picks, book pages and lists says how well a book suits you and why. Explore deals out one book at a time, where a like changes what comes next and a pass drops only that book. Today collects rails such as Because You Loved, New for Your Taste and Next in Your Series. Not for me on a book card keeps a book out of future Picks and Today, and you can name up to three books on your taste page that you want to steer away from.

There’s also the weekly Siftivo Reading Index, a fiction and nonfiction chart that currently runs on weekly bestseller lists, plus pages for 24 award bodies and lists from outlets and public figures. For the log, Siftivo tracks progress by pages, percent or time, keeps a private journal with a heatmap, and lets you mark a book DNF with an optional reason.

Where Margins wins

At Margins the design is the product. You can choose the cover that matches your edition, sort your library by color, get hand-illustrated monthly recaps, and turn your profile picture into a sketched portrait. It holds a 4.9 average on about 19,400 US App Store ratings and a 4.9 on Google Play, and Apple’s App Store editors have featured it. Siftivo isn’t trying to compete on that front, and if how your shelf looks matters to you, Margins is the app.

It also does more for the habit of reading. The blocker and timer are the headline, and around them sit Strava-style goals, stats and streaks. Siftivo has no yearly reading goals or challenges. Margins runs on Android, comes in 14 languages, rates books in quarter stars, and imports from StoryGraph and Fable as well as Goodreads, with Fable imports bringing over your current progress. Margins also says it doesn’t sell or share your data with advertisers.

A few honest caveats. Margins doesn’t advertise a web app for tracking, so it’s a phone-first experience. Kindle sync hasn’t shipped, though its September 2026 rebuild was meant to prepare for it. And it doesn’t publish exactly what the paid subscription adds.

Switching, or using both

Both apps import from Goodreads. Siftivo takes your Goodreads export through the web app and brings in read, currently reading and want to read, with your ratings and reviews. It leaves out custom shelves, a DNF shelf, start dates and date added. If your library lives in StoryGraph or Fable today, Margins can take it directly. If you’re also weighing StoryGraph itself, we’ve compared it with Siftivo too.

The two also sit together comfortably. Use Margins to track and to keep your phone quiet while you read, and use Siftivo to decide what that next book should be.
