Verdict
The clearest difference is price: SideBooks at Free against ComicShare's $3.99. SideBooks also leads on update cadence (every 9 days vs every 4 weeks) and iOS requirement (9.0 vs 12.0). ComicShare's advantage is review sentiment (85% vs 72%) and chart position (#101 vs unranked). On rating, ratings volume, ads and in-app purchases there is nothing between them.

SideBooks is free to download; ComicShare costs $3.99 up front. SideBooks sells 1 one-off in-app purchase and ComicShare sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
SideBooks holds the better App Store score, 4.6 against 4.4. Both are backed by a comparable volume of ratings — 97 and 47 respectively. Written reviews complicate that: 72% of SideBooks's written reviews are positive against 85% of ComicShare's, so the app with the better star average is not the one people write more warmly about.
SideBooks ships an update every 9 days, ComicShare every 4 weeks. The most recent releases landed on September 23, 2026 and September 24, 2026 respectively.
