Coming from ReadEra, what changes.

Every device, one purchase

ReadEra is an Android app. Tomen runs in any browser today, as a Windows app and an Android app, and one Plus purchase covers all of them. Your place, highlights and settings follow you between a phone, a tablet and a PC through a Tomen account. If you only ever read on one phone, that is worth less to you than it sounds; if you read on two things, it is the whole point.

The page is set, not just displayed

ReadEra shows a book cleanly and gives you settings to adjust it. Tomen re-sets every book in its own typography, with the type and measure chosen once and tuned to the screen, so a messy EPUB reads as well as a designed one and nothing has to be adjusted per book. Nine themes, including ones drawn for e-ink, and a reading voice that reads aloud on Android.

Comics, and a Calibre library

CBZ, CBR, CBT and CB7 open as comics on the same shelf as the books, with spreads, right-to-left reading for manga, chapters from the ComicInfo file, and a minimap when you zoom into a page. A Calibre library comes in four ways, from adding the folder to keeping it in Dropbox and reading it in place. The Calibre guide has each one.

Nothing to install to try it

Go to read.tomen.app, drag a book in, read. No account, no ads, no tracking, and the free tier is complete: every format, the themes, contents, search, sorting, gestures. Plus adds the things you do inside a book, not the reading itself. The shelf you make in the browser is the one the apps sign into.

What you give up

• Documents. ReadEra reads PDFs as text and opens Word files and the like. Tomen reads a PDF as pages, the way it reads a comic, and does not open office documents.
• A library that finds itself. ReadEra scans the device for books on its own. Tomen asks you to add a file or a folder once, and watches that folder from then on.
• Price. ReadEra is free, and its Premium is a small one-time purchase for one platform. Tomen Plus is $49, once, for every platform.
• Your notes. Tomen imports highlights from Kindle, Kobo, Apple Books, Readwise, Moon+ Reader, KOReader and Boox, but not yet from ReadEra. If you have notes there, keep ReadEra installed until it does.

If you read on one Android phone, your books are PDFs as often as EPUBs, and ReadEra already does what you need, stay. This page is for people who read on more than one device, or who care how the page is set.
