Verdict
The clearest difference is in-app purchases: Cardiac Stress Test Calculator at none against Quiet Time's 1. Cardiac Stress Test Calculator also leads on update cadence (daily vs every 5 weeks). Quiet Time's advantage is iOS requirement (15.1 vs 17.5). On price, ads and device support there is nothing between them.
