Verdict

The call

The clearest difference is rating: SoundEcho at 4.3 against Sonar Islands's 3.5. SoundEcho also leads on review sentiment (100% vs 60%) and monetization model (free vs subscription). Sonar Islands's advantage is ratings volume (83 vs 3) and iOS requirement (12.5 vs 17.0). On price, update cadence, ads and in-app purchases there is nothing between them.
