Picking up where ComicBookLover left off
ComicBookLover was one of the first comic readers built for the iPad — simple viewing tools and a genuinely logical way to organize a collection so you always knew what you had. When it stopped working with iOS 8, nothing that came after quite captured the same spirit.
Longbox Reader started as a side project in 2017, stalled when the original technology choice became a wall rather than a foundation. In 2022, the focus shifted to what would become Digital Longbox — a proper scanner and metadata editor for a local comic collection — and a working prototype came together before performance problems stalled it again. Work resumed in 2025 and led to the apps you can download today.
Partway through that second stall, in 2024, YACReader came up — a free, open-source comic manager and reader that's been refined since 2009 and is considerably more mature than what's here today. It came close to ending the project outright. What settled it was a genuine difference in how the two handle a library, not a claim to do it better: YACReader mirrors your actual folder structure, so you browse nested folders — however deep, however you've organized them — much like a file manager. Digital Longbox takes a different approach on purpose: one folder per series, matched automatically against a shared metadata service and organized into a proper series-and-issue database rather than a raw folder tree. That difference felt worth finishing.
Have one big comic folder and just want to browse it like a file manager? Try YACReader first — it's free, mature, and built exactly for that kind of folder-tree browsing. Digital Longbox and Longbox Reader are still actively evolving, with bug fixes and improvements ahead, but they take a different approach to organizing a library and will take time to reach that same level of polish.
Along the way, a handful of very different tools shaped how these apps think about your files, without copying any of them directly:
WinAMP + CDDB
Just knew which songs matched your files. That kind of quiet, automatic recognition is what comic scanning aims for.
Media Companion
A Windows tool for generating metadata for local media files — the inspiration behind editable, enrichable comic metadata.
Plex
Serves your own local media across your network. Digital Longbox does the same thing, for comics instead of video.
