Verdict
The clearest difference is review sentiment: Curly at 100% against API Client's 0%. Curly also leads on update cadence (every 2 days vs every 10 days) and monetization model (free vs free with in-app purchases). API Client's advantage is iOS requirement (14.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
