# KomiX vs Shelf Scanner.

The clearest difference is review sentiment: KomiX at 67% against Shelf Scanner.'s 9%. KomiX also leads on in-app purchases (none vs 3) and update cadence (every 2 months vs every 7 months). Shelf Scanner.'s advantage is price (Free vs $1.99) and rating (4.5 vs 2.8). On ads there is nothing between them.

Shelf Scanner. is free to download; KomiX costs $1.99 up front. Shelf Scanner. sells 3 in-app purchases, starting at $4.99 per 7 days. KomiX asks for nothing beyond the download.

Shelf Scanner. holds the better App Store score, 4.5 against 2.8. That said, the two scores are not equally well evidenced: Shelf Scanner. has 262 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 67% of KomiX's written reviews are positive against 9% of Shelf Scanner.'s, so the app with the better star average is not the one people write more warmly about.

KomiX ships an update every 2 months, Shelf Scanner. every 7 months. The most recent releases landed on October 1, 2026 and October 17, 2026 respectively.
