Verdict
The clearest difference is review sentiment: iCodex at 100% against SystemBatteryAnalysis's 46%. iCodex also leads on rating (5.0 vs 4.4). SystemBatteryAnalysis's advantage is ratings volume (194 vs 1) and update cadence (every 6 days vs every 3 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.
