# Operation WarShell vs Slab

The clearest difference is rating: Slab at 5.0 against Operation WarShell's 4.0. Slab also leads on ratings volume (8 vs 1). Operation WarShell's advantage is in-app purchases (none vs 1). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. Slab sells 1 one-off in-app purchase. Operation WarShell asks for nothing beyond the download.

Slab holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: Slab has 8 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
