Verdict
The clearest difference is rating: Knockline at 5.0 against Harmony Decision Maker's 4.3. Knockline also leads on in-app purchases (none vs 7) and update cadence (every 3 days vs every 3 months). Harmony Decision Maker's advantage is ratings volume (8 vs 1) and iOS requirement (12.0 vs 15.0). On price, ads and device support there is nothing between them.
