# Sound vs Structural Floor Vibration

The clearest difference is ads: Structural Floor Vibration at none against Sound's shown. Sound's advantage is iOS requirement (15.8.3 vs 17.0). 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.
