# Gridder vs Color Study

The clearest difference is in-app purchases: Gridder at none against Color Study's 7. Gridder also leads on iOS requirement (12.0 vs 16.6). Color Study's advantage is ratings volume (512 vs 1) and chart position (#143 vs unranked). On price, rating, ads and device support there is nothing between them.

Both are free to download. Color Study sells 7 in-app purchases, starting at $2.99 per month. Gridder asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for Gridder against 4.9 for Color Study. That said, the two scores are not equally well evidenced: Color Study has 512 ratings behind it against 1, so its average is the more settled of the two.
