Verdict
The clearest difference is in-app purchases: iClock at none against Heart Analyzer's 7. iClock also leads on rating (5.0 vs 4.7) and review sentiment (100% vs 84%). Heart Analyzer's advantage is ratings volume (22K vs 4). On price, update cadence, ads and device support there is nothing between them.
