Verdict
The clearest difference is review sentiment: Rex Music at 100% against Stem Split's 32%. Rex Music also leads on rating (5.0 vs 4.5) and iOS requirement (13.0 vs 16.4). Stem Split's advantage is ratings volume (1.4K vs 6) and update cadence (every 8 days vs every 4 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.
