# Guroku vs C4K

The clearest difference is price: Guroku at Free against C4K's $2.99. Guroku also leads on rating (4.8 vs 4.0) and ratings volume (48 vs 1). C4K's advantage is in-app purchases (none vs 1) and review sentiment (100% vs 86%). On ads, device support and iOS requirement there is nothing between them.

Guroku is free to download; C4K costs $2.99 up front. Guroku sells 1 one-off in-app purchase. C4K asks for nothing beyond the download.

Guroku holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: Guroku has 48 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 86% of Guroku's written reviews are positive against 100% of C4K's, so the app with the better star average is not the one people write more warmly about.
