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.

Verdict
The clearest difference is rating: MOBS at 4.5 against Longbox's 4.0. MOBS also leads on in-app purchases (none vs 3) and ratings volume (13 vs 4). Longbox's advantage is review sentiment (100% vs 78%). On price, update cadence, ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Longbox sells 3 in-app purchases, starting at $1.99 per month. MOBS asks for nothing beyond the download.
MOBS holds the better App Store score, 4.5 against 4.0. Both are backed by a comparable volume of ratings — 13 and 4 respectively. Written reviews complicate that: 78% of MOBS's written reviews are positive against 100% of Longbox's, so the app with the better star average is not the one people write more warmly about.
MOBS ships an update every 5 days, Longbox every 3 days. The most recent releases landed on October 24, 2026 and October 20, 2026 respectively.
