Longbox is a comic reader for people who already have the comics. Point it at your CBZ, CBR and PDF files and it opens them. No account, no upload, no waiting for a library to sync before you can read anything. READING • Fit to width, height or whole page — whichever suits the book • Turn your phone or iPad sideways to read two pages at once, and art drawn across a spread still gets the screen to itself • Pinch to zoom anywhere, double-tap to snap • Right-to-left for manga, set per series and remembered • Night and sepia filters, plus in-app brightness that leaves your system setting alone • Opens on the page you left, every time • Entirely offline — nothing is streamed unless you ask for it YOUR LIBRARY • Import from the Files app — anything on your iPhone or in iCloud Drive • However many comics you own — a hundred or ten thousand, there's no limit • Issues group into series on their own • Search, favourites and reading history • Up to eight libraries, any of them behind a passcode • Reading streaks and a leaderboard, if you want to be on it ALL OF THAT IS FREE The reader is never behind a paywall. Not the filters, not the fit modes, not the reading direction, not reading offline. There's no cap on how many comics you keep, either. If it opens a comic, it costs nothing. LONGBOX PREMIUM • Connect a Komga, Kavita or OPDS server — browse it, read from it, download for offline • Hide comics you'd rather not see, without touching the server • Browse your Dropbox from inside Longbox: a single issue or a whole folder, without leaving the app • Sharpening and upscaling for scans that need it • Beta features first – Panel by panel (alpha) — splash pages and complicated layouts often won't detect • Automatic metadata — publisher, year, creators and characters • EPUB novels — contents, adjustable type, themes and highlighting • Unlimited libraries • Smart Lists that keep themselves current • Your place follows you — across your devices, and in step with your server both ways • Your own picture as the app background • Seven accent colours, each with its own app icon Comics you have already downloaded from a server stay readable forever, even if Premium lapses. Paying us was never what made them yours. PREMIUM PRICING Longbox Premium is available as a one-time purchase, or as a subscription billed monthly or yearly with a 7 day free trial.
