justRead vs BookFusion: a cloud library on web, iOS and Android, or a reader made for the iPhone

BookFusion
Cloud library and reader for web, iOS and Android
Which should you pick?
Pick justRead.app if
you read on iPhone and iPad, want to pay once, and want voices that run on the device, lock-screen widgets and goals. It costs $79.99 once, after a 14-day trial.
A cloud library and a reader
Both read your own DRM-free books. They differ in where the books live and how you pay.
BookFusion is a cloud library first. You sign in, upload your books, and read them on iOS, Android, the web and E Ink tablets. Plans are subscriptions, from $1.99 a month.
justRead is a reader for iPhone and iPad. It reads a book in place from the folder you chose, syncs through iCloud, and sells a one-time purchase at $79.99 next to its monthly and yearly prices.
Since version 1.44.1, BookFusion's iPhone app also reads unlimited books on the device without an account. So its 10-book free limit applies to the cloud library, not to reading on the phone.
What each app costs
BookFusion is free to start and then a subscription. justRead has a trial, then a paywall with a one-time option.
BookFusion: a free plan with a small cloud library
The Free plan holds 10 books in the cloud library, with a 50 MB file cap and 2 new uploads a month once it is full. Since version 1.44.1 the iPhone app also reads unlimited books on the device without an account.12
BookFusion: three paid plans
Casual costs $1.99 a month or $18.99 billed yearly, Advanced $4.99 or $47.99, and Power $9.99 or $95.99. They hold 5 GB, 20 GB and 100 GB. The pricing page shows no one-time purchase.1
BookFusion: early adopter pricing
The pricing page marks these as early adopter prices, shows $2.99, $7.99 and $14.99 beside Casual, Advanced and Power, and says to lock in the rate before future increases.1
justRead: free for 14 days, then paid
justRead costs $4.99 a month, $29.99 a year or $79.99 once, after a 14-day trial. Of the two apps, only justRead has a one-time price.134

-
Find your book files
BookFusion accepts only DRM-free uploads and keeps them in its cloud library. Your original files, such as the ones in your Calibre library, are what you add to justRead.1
-
Convert what justRead cannot open
justRead has no import for MOBI, AZW3, FB2 or DjVu files. Convert them to EPUB first, for example with Calibre.4
-
Add the books to justRead

What BookFusion's users say
Five App Store reviews from the US store, quoted as written. Three praise BookFusion and two are about its price. The 10-book review dates from December 2025, before version 1.44.1 added reading on the device without an account.
BookFusion is absolutely the superior option over NaturalReader, ElevenReader, Speechify, Adobe and others.
The devs are very responsive in their discord and subreddit as well.
The best part is the Obsidian plug-in, which imports all of your highlights in a neat fashion and is fully customizable.
One time payment is a necessary feature for those who cannot pay monthly subscription fees.
Only 10 books are allowed for a free version, which basically makes it obligatory to pay.
