# Quick Chess vs eyeStudy

The clearest difference is in-app purchases: eyeStudy at none against Quick Chess's 7. eyeStudy also leads on iOS requirement (13.0 vs 15.0). On price, ads and device support there is nothing between them.

Both are free to download. Quick Chess sells 7 one-off in-app purchases. eyeStudy asks for nothing beyond the download.
