Editor's Overview

Quire is a ebook reader application developed by vitofico, packaged as a single Android APK of version 2026.1 weighing in at 23.6 MB. The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

Install Checklist

Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
File size is a light 23.6 MB, so it installs quickly even on modest connections.
This build is signed by "vitofico" — always verify the developer name matches what's listed on the app's official store page before installing an update.
After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

Quire is a native Android EPUB reader for people who self-host
calibre-web.

It browses your library over OPDS, downloads books on demand, renders
them with Readium, and syncs reading progress (and later bookmarks) to
a small companion server you run yourself (Quire Server, included).

Features:
- OPDS catalog browsing and search
- EPUB reading with Readium (font, theme, line-height controls)
- Reading progress sync across devices via your own Postgres
- Multi-user from day one
- One credential: your existing calibre-web account

Privacy:
- No analytics, no crash reporting, no third-party SDKs
- Network calls go to your calibre-web and your sync server only
- Credentials stored in Android Keystore

Source code, server, and documentation:
https://github.com/vitofico/quire

Optional AI features (off by default): when your Quire Server administrator
configures an AI endpoint (such as a self-hosted Ollama or a third-party
provider) and you opt in from Settings, Quire shows generated book
insights — author, summary, series, themes, craft notes, comparative
anchors, and book-club style discussion prompts — grounded with
citations from Wikipedia and OpenLibrary. A separate Library Insights
screen builds a personal reader profile from your finished books and
suggests further reads (both from your own library and via OpenLibrary
discovery). No AI request leaves your network until you explicitly opt
in, and a single tap in Settings deletes the cached profile.

Frequently Asked Questions

Is Quire free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does Quire require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is Quire safe to install?
We link to the exact APK published by vitofico. We do not modify the file. Still, as with any sideloaded app, scan it with a reputable antivirus before opening it, and only grant permissions the app genuinely needs.

How do I update Quire?
Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).

Why is the app not installing?
Common causes: not enough storage, an older Android version than 4.1+, or a conflicting build already installed. Free up space, check your OS version, and uninstall any previous copy before retrying.
