Hi there! I've been working on Calibre View, a simple (free) iOS app for browsing Calibre libraries stored in Dropbox, Google Drive, One Drive, WebDAV, iCloud or the Files app, and I'd love some beta testers.

Most Calibre apps on iOS are great (I use CalibreSync a ton), but I wanted something more like the desktop library view: clean lists, easy sorting, quick filtering, and a simple way to grab a book in whatever format you already have with an iOS-native feel.

Here's a quick demo (from a few versions back, but covers most features): https://www.youtube.com/watch?v=osoQ-oFrpm0

What this app does:

Connects to Calibre libraries in Dropbox, Google Drive, OneDrive, WebDAV, iCloud, or the Files app
Handles big libraries (tested up to ~15,000 books; loads in ~20 seconds on iPad Pro)
Lets you choose which columns to show, including custom ones
Sort by any field on tap (title, tags, custom columns, etc.)
Book detail view with cover, metadata, and download/share options
Tap an author, series, or tag to instantly filter the whole library from the details page
Great for FanFicFare users, tag filtering for characters/ships/tropes works really well
Full-library search with near-instant results
Supports multiple libraries across different cloud services
Optional horizontal scrolling for small screens/orientations
Offline browsing once metadata is downloaded (covers and books still require connection)
Light and dark mode

Right now it's basically "browse → filter → download," and it won't make any changes to your Calibre library as it's read-only. To me, that simplicity is the point.

If you'd like to help test it, here's the TestFlight link: https://testflight.apple.com/join/A4bvtPMb

I've tested it with my own libraries on Drive and Dropbox and it's working well, but I'd appreciate feedback from different setups. Very large libraries may take longer to load or hit memory limits, but anything under 15k should be fine. (And maybe up to 50k, idk but feel free to test!)

Change Log

Spoiler:

Thanks to anyone willing to poke at it!
