Best Book App for Fantasy Readers (2026)

The best book app for fantasy readers is Hardcover. It has a series tracker, series pages that recommend similar series, and recommendations you can steer by world and series position, which covers both of the problems we get into below. Siftivo is the better pick if you’d rather start from the three books you love than from a series page, and Goodreads still has more reviews to read before you commit to book one of something long.

Siftivo is ours, so we’ve tried not to flatter it here. Everything about Hardcover, Goodreads and Audible comes from their own sites, store listings, help pages and team reports.

The hard part starts when the series ends

Finding a fantasy book is easy enough, but fantasy rarely comes one book at a time. You’re three books into one series, waiting on the next of another, and have a fourth you abandoned at book two and keep meaning to go back to.

That leaves fantasy readers with two problems most other readers don’t have. The first is keeping track of where you are across several series at once. The second, and the harder one, is what to read when a series you loved is finished. “More fantasy” covers everything from a cozy tea-shop novel to a grimdark war saga, and the next pick usually commits you to another four or ten books. A wrong guess costs you a lot more than an evening.

So the apps below are ranked on how well they handle both. Series tracking is the easy test. The after-the-series pick is where they really differ.

1. Hardcover

Best for

tracking many series and finding the next one

Price

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

Platforms

Web, iOS, Android

Visit Hardcover

Hardcover is the strongest fit here for genre readers. Its Series Tracker can mark read books across all your series at once, and series pages now have a Similar tab that recommends related series, which is the after-the-series question answered on the page where you ask it. Its Vibes recommendations come in versions every logged-in reader gets, like one built from your last five 5-star reads, and Supporters can build their own, steered by world, whether fantasy, science fiction or the real world, by series position, popularity and a typed description. Its most-read books are Dungeon Crawler Carl titles, and the team reports tuning its recommendations against a LitRPG and progression fantasy benchmark. Tracking covers half stars, DNF and Paused statuses, goals by pages or hours, and a reading journal, and it imports from Goodreads and StoryGraph.

The catch is that building your own Vibes and the personalized For You view are Supporter features. There’s no direct Kindle sync, and e-reader sync for Kobo and KOReader comes from community-built tools rather than Hardcover itself. Book clubs and buddy reads were still in team alpha testing as of its October 2026 report.

2. Siftivo (ours)

Best for

picks from three books you love, plus Next in Your Series

Price

No paid plan

Platforms

Web, iOS

Visit Siftivo

Siftivo starts from three books you love rather than from a series, which helps when what you loved about a series wasn’t the genre so much as the voice or the found family. Each Daily Pick credits the favorite behind it, so you can tell whether a suggestion is riding on your epic favorite or your quieter one. Series pages list the books in reading order, and the Next in Your Series rail on your Today page puts the next unread book of any series you’ve started in front of you, next to rails like From Authors You Love. Author pages show a biography and the author’s books, and award pages cover 24 award bodies if you like to read down a shortlist. Search takes a plain description, so “slow magic system, political intrigue, no prophecy” is a fair query.

The catch for series readers is that Siftivo has no per-series progress count. Series pages show the order and the Today rail shows what’s next, but if you’re juggling six series, Hardcover’s tracker keeps better count. The Goodreads import skips custom shelves, so if you sorted series into shelves there, that structure stays behind. It has no Android app either.

3. Goodreads

Best for

ratings and reviews on almost every book

Price

Free

Platforms

Web, iOS, Android, Kindle

Visit Goodreads

Goodreads has the scale nobody else here has. It says more than 75 million members have shelved more than 2.2 billion books, so almost any fantasy book, even the seventh in a long series, has ratings and reviews to read before you start. A 2019 help post describes a Readers Also Enjoyed section on book pages, you can ask for recommendations based on any one of your shelves, and the Kindle app can mark a book Currently Reading when you start it and Read when you finish. Its Did Not Finish shelf, added in March 2026, keeps your rating, review and how far you got, which is handy for the series you stalled on.

The catch is that ratings are whole stars, and Goodreads says it has no plans to add half stars. It doesn’t advertise mood filters, content warnings or vibe search in its app store feature lists. The most recent explanation of how its recommendations work on its help site dates from November 2019. Goodreads is owned by Amazon, which matters to some readers and not at all to others.

4. Audible

Best for

one Premium credit per audiobook, whatever its length

Price

Standard $8.99/mo, Premium $14.95/mo or $149.50/yr

Platforms

iOS, Android, Alexa devices, Fire tablets, Kindle, Sonos

Visit Audible

Audible is on this list for one reason that suits fantasy in particular. A Premium credit buys any audiobook regardless of its length or list price, so a forty-hour epic costs the same credit as a short novel. Books you buy with credits or cash stay yours after you cancel, and Whispersync for Voice lets you switch between a Kindle ebook and its audiobook, which helps when a series is long enough to read some of it and listen to the rest. Premium also includes the Plus Catalog, thousands of titles to stream or download while you’re a member.

The catch is that Audible is a paid membership after the trial. Premium credits expire 12 months after they’re issued or when you cancel, Standard members lose their monthly selections when they cancel, and Plus Catalog titles stay only while you’re a member and the title stays in the catalog. Pair it with a tracker for the series itself.

My pick

If you read several series at once and the question you keep asking is what comes next, use Hardcover. Its series tracker and Similar tab answer that more directly than anything else here.

If what you loved about a series is hard to put into genre terms, start with Siftivo, give it your three favorites, and use Next in Your Series to keep the current ones moving. Keep Goodreads open for reading reviews before you commit to book one of anything long, and if you listen more than you read, Audible’s credits favor the long books fantasy is full of.

What I’d do today

1. List every series you’re partway through, with the next book in each.
2. Add them to Hardcover’s Series Tracker and open the Similar tab on the one you most recently finished.
3. Give Siftivo your three favorite fantasy books, and include one that isn’t the obvious pick, so the reason lines have something to separate.
4. Before you start a new series, read a handful of Goodreads reviews of its second book. Reviews of book two tell you more about whether a series holds up than reviews of book one.
