Verdict
The clearest difference is rating: Sound & Soothe at 5.0 against QuickVibrator's 2.8. Sound & Soothe also leads on ads (none vs shown) and review sentiment (100% vs 68%). QuickVibrator's advantage is update cadence (every 4 months vs every 44 months) and monetization model (free vs free with in-app purchases). On price and in-app purchases there is nothing between them.
