Verdict

The call

The clearest difference is rating: Complete Ear Trainer at 4.7 against Otonic's 4.4. Complete Ear Trainer also leads on ratings volume (202 vs 5) and review sentiment (85% vs 67%). Otonic's advantage is update cadence (every 5 days vs every 2 weeks) and iOS requirement (12.0 vs 17.5). On price, ads, in-app purchases and monetization model there is nothing between them.
