# Concepts vs Art Set 4

Concepts and Art Set 4 both sit at 4.7 stars, but that hides the real split: 77% of Concepts's written reviews are positive against 63% of Art Set 4's. Concepts also leads on chart position (#208 vs unranked) and device support (3 vs 1). Art Set 4's advantage is update cadence (every 6 days vs fortnightly) and iOS requirement (12.4 vs 15.0). On price, rating, ratings volume and ads there is nothing between them.
