# Gridular vs C4K

The clearest difference is price: Gridular at Free against C4K's $2.99. Gridular also leads on rating (4.8 vs 4.0) and ratings volume (594 vs 1). C4K's advantage is in-app purchases (none vs 10) and ads (none vs shown). On device support there is nothing between them.

Gridular is free to download; C4K costs $2.99 up front. Gridular sells 5 one-off in-app purchases. C4K asks for nothing beyond the download.

Gridular holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: Gridular has 594 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 90% of Gridular'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.
