# ScreenRuler vs VIN Checker

The clearest difference is ads: VIN Checker at none against ScreenRuler's shown. VIN Checker also leads on iOS requirement (13.0 vs 15.1). 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.
