Foldbook

Your comics, manga and books, read right where you keep them.

For Android, iPhone and iPad

  1. A library that sorts itself

    Series are grouped by folder, covers show up on their own and volumes line up in order, numbers included.

  2. A page for every series

    The summary, the genres, the trailer, and a button to pick up where you were.

  3. Back to the right page

    A volume started on your tablet continues on your phone, page for page.

Reading

The page turns under your finger.

It curls, shows its back and follows your hand, like a real sheet of paper.

Formats

Whatever you have, it reads.

Your library

Plug in what you already have.

Foldbook reads your files where they are. It doesn't sell or supply any books.

01

A NAS

Synology, QNAP, or a Mac or PC sharing a folder over SMB. Volumes open page by page, with no download first.

02

iCloud Drive and Files

Pick a folder in the Files app and it becomes a library, read in place, never copied.

03

WebDAV and OPDS

Nextcloud, Synology WebDAV, and the Komga, Kavita and Calibre-Web catalogs.

04

Your own files

A CBZ from AirDrop or a downloaded PDF: open it with Foldbook and it joins your library.

On iPad

Two pages, like paper.

In landscape, the iPad shows the full spread and opens wide pages whole.

iPhone Duo

Folded or open, it follows the Duo.

  1. The Duo bar

    Folded, Foldbook puts its tabs and the time in the Duo's vertical bar. Your library gets the rest of the screen.

  2. Cover mode

    Folded, the Duo shows the cover of the volume you are reading, like a closed book. Open it to pick up again.

  3. Unfold and read

    The spread opens where you left off, both pages side by side like a book lying flat.

  4. Half open, like a book

    Held like a book, the Duo keeps each page on its own side of the hinge.

And the rest

Made for long reads.

Novels too

EPUBs in paper, sepia or night themes, with fonts, highlights, notes and a table of contents.

Offline

Keep a volume or a whole series for the flight, and remove it with a tap once read.

Panel by panel

On an iPad in landscape, the panel large on one side and the whole page on the other.

Your reading follows you

With the optional account, your progress, bookmarks and notes move between devices. Without one, they stay on your NAS.

One subscription, and your whole family reads.

The comics you already own, your family doesn't have to buy again. You invite them, choose what each person sees, and they read for free from their own home. With Foldbook+, your library also follows you on 4G, at work or on holiday.

Questions

Before you start.

Which sources can I add?

A NAS folder over SMB (Synology, QNAP, or a Mac or PC sharing a folder), a WebDAV server (Nextcloud, Synology), a folder from iCloud Drive or the Files app, an OPDS catalog (Komga, Kavita, Calibre-Web) and the files on your device. Tap “+” in the library to add one.

Which formats can it read?

CBZ, CBR (RAR4 and RAR5), CB7, PDF and EPUB.

My NAS doesn't show up or refuses to connect.

Check that your device and NAS are on the same network and that SMB sharing is on. On iPhone and iPad, Foldbook also needs access to the local network (Settings › Privacy & Security › Local Network). Away from home, use WebDAV, a VPN, or Foldbook Server.

Do I need an account?

No. Without one, your progress goes into a small file, .folio-progression.json, at the root of the share of your first NAS library, and every device reading that share finds it there. The optional account keeps your setup, progress and notes for all your devices.

How do I delete my account?

In Foldbook, Settings › Account › Delete my account. Everything the account keeps is erased right away.
