Verdict
The clearest difference is in-app purchases: Hacker Clock at none against Stress Matrix's 1. Hacker Clock also leads on device support (3 vs 1) and iOS requirement (12.0 vs 16.2). Stress Matrix's advantage is update cadence (daily vs every 15 months). On price and ads there is nothing between them.
