Verdict
The clearest difference is in-app purchases: EVY INSIGHT at none against HeartMath's 5. EVY INSIGHT also leads on device support (3 vs 1) and iOS requirement (13.0 vs 26.0). HeartMath's advantage is update cadence (every 3 weeks vs every 2 months). On price and ads there is nothing between them.
