Verdict
The clearest difference is review sentiment: Sharpe Performance at 100% against Kahunas's 19%. Sharpe Performance also leads on rating (5.0 vs 3.3). Kahunas's advantage is ratings volume (77 vs 1) and update cadence (monthly vs every 3 months). On price, ads, in-app purchases and monetization model there is nothing between them.
