Verdict
The clearest difference is in-app purchases: Comic Book Viewer at none against MOBI Reader's 4. MOBI Reader's advantage is update cadence (monthly vs every 3 months) and rating (4.0 vs 3.8). On price, review sentiment, ratings volume and ads 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. MOBI Reader sells 4 one-off in-app purchases. Comic Book Viewer asks for nothing beyond the download.
MOBI Reader holds the better App Store score, 4.0 against 3.8. Both are backed by a comparable volume of ratings — 135 and 188 respectively. Written reviews complicate that: 71% of Comic Book Viewer's written reviews are positive against 63% of MOBI Reader's, so the app with the better star average is not the one people write more warmly about.
Comic Book Viewer ships an update every 3 months, MOBI Reader monthly. Both last shipped on November 1, 2026.
