# BPK vs Structural Floor Vibration

The clearest difference is rating: Structural Floor Vibration at 5.0 against BPK's 4.2. Structural Floor Vibration also leads on monetization model (free vs ad-supported). BPK's advantage is ratings volume (5 vs 1) and iOS requirement (15.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
