Verdict

The call

The clearest difference is rating: SAUL at 5.0 against Clear Wave's 4.6. SAUL also leads on iOS requirement (14.0 vs 17.0). Clear Wave's advantage is ratings volume (37K vs 4) and chart position (#26 vs unranked). On price, ads, in-app purchases and monetization model there is nothing between them.
