# RGB Test vs 测屏幕

The clearest difference is ads: 测屏幕 at none against RGB Test's shown. 测屏幕 also leads on iOS requirement (15.6 vs 26.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
