Trace — Offline EPUB Reader

Built for reading AO3 EPUBs

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Read your downloaded AO3 EPUBs in a private, comfortable library built for fanfiction, with offline reading, rich organisation and optional sync to an online library. Trace Reader is a private, unofficial reader for EPUBs you download from AO3. Import a story and read it comfortably offline, with the metadata and organisation fanfiction readers actually need. NO AO3 LOGIN - Keep your account details private. You should never trust a third party with your AO3 login details and this app will never ask you for them. I built this for accessible reading tailored to offline AO3 reading because Apple Books wasn't quite enough. Choose paged or continuous scrolling, adjust the type and spacing, and read in Paper, Sepia, Night or High Contrast themes, with accessible fonts. BUILD A LIBRARY THAT FEELS LIKE YOURS • Keep stories as Saved, Reading, Paused, Caught up, Finished or Dropped • Add ratings, personal tags and private notes • Search and filter by fandom, relationships, characters, warnings, series and more • Import individual EPUBs or choose a folder that will automatically load EPUBs once you download them from AO3. • Keep previous EPUB versions and restore one when needed NO ACCOUNT NEEDED Reading, importing and organisation work offline. Your EPUB files and story text stay on your device with no limitations on library size or organization features. TRACE SYNC IS OPTIONAL ADD ON Connect a free Trace account to sync up to 100 stories, restore library details and reading progress on a new device, and access your reading library from any browser. Trace Unlimited adds unlimited Reader sync and private reading Stats. Trace also gives you access to the Trace extension, which lets you track your online reading in the same way you track your EPUB reading, storing it all in the same online library. A subscription is never required to read, import or organise EPUBs on this device. EPUB files are not included in sync right now. Trace Reader is an independent, unofficial app. It is not affiliated with or endorsed by the Organization for Transformative Works or Archive of Our Own.
