Verdict

The call

The clearest difference is monetization model: HeartMath at freemium against Coherence's subscription. HeartMath also leads on ratings volume (4.6K vs 566). Coherence's advantage is update cadence (every 4 days vs every 3 weeks) and review sentiment (84% vs 73%). On price, rating, ads and in-app purchases there is nothing between them.
