Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

Comic Book Viewer ships an update every 3 months, MOBI Reader monthly. Both last shipped on November 1, 2026.
