### Mobi, Kindle and FB2 files

## Where justRead is the better pick

Five places where justRead leads.

## How we checked

justRead.app makes justRead. Every justRead cell comes from the app's source code at the 5.6 release.

The five rivals' cells come from each maker's own pages, release notes and US App Store listing, and from public source files where the app is open source. Each source was re-read on 28 October 2026.

"Not stated by the developer" means the store text and the maker's pages list nothing either way. It describes those pages, not the app.

We did not install any of these apps or test them on a device. Each line describes what a maker says or what a source file shows.

Anx Reader's cells describe store version 1.14.0. Its GitHub page lists newer beta releases.

KyBook 3's maker facts come from an Internet Archive copy of its site captured on 22 December 2024, because the live site did not answer.

Prices change. Readest's and BookFusion's come from their pricing pages, KyBook 3's and Anx Reader's from the US App Store, Yomu's from its help pages, and justRead's from its own site.
