ReadEra - book reader pdf epub

What it is

ReadEra is a reader app from READERA LLC, listed under Books & Reference. It is built for opening files you already have rather than selling you books. The listing names PDF, EPUB, Word (DOC, DOCX, RTF), Kindle formats (MOBI, AZW3), plus DJVU, FB2, plain text, ODT and CHM. It is free, rated Everyone, first listed in March 2017, and was updated on 2026-10-29.

What it does well

The headline claims are practical. The developer states the app has no ads and no internal purchases, and that it works offline without asking you to register. Those three points are the sort a reader cares about.

For PDFs, the listing mentions margin cropping and a single-column mode that splits a scanned two-page spread into separate pages. For text formats, you can adjust font, size, boldness, line spacing and hyphenation, and pick a color mode such as day, night or sepia. Footnotes print at the bottom of the page.

Library tools are covered as well. The app detects books on the device, groups them by author and series, and offers reading lists (To Read, Have Read, Favorites) plus collections that work like bookshelves. It does not copy files into its own store, according to the listing, which keeps memory use down.

The rating data is excellent. ReadEra holds 4.86 from 1,599,873 ratings with 50,000,000+ installs. A full 90.9% of ratings are five stars, and 1.1% are one star.

Where it falls short

There is little in the ratings to complain about, so the cons here are about what the listing leaves unsaid. It does not mention syncing across devices, so a reader who moves between a phone and a tablet should check that before relying on it. It also does not describe audiobook support or reading aloud.

The tool is also about files you supply. If you want a shop inside the app, nothing in the listing points to one.

Who it suits

Anyone with a pile of PDFs, EPUBs and Word documents who wants a single, quiet app to read them offline. The ratings suggest very few people are let down, and a no-ads, no-account approach is a clear plus for privacy-minded readers.
