Verdict
The clearest difference is price: FreeWillow at Free against KNX Pro Tester's $17.99. FreeWillow also leads on iOS requirement (15.1 vs 26.4). KNX Pro Tester's advantage is update cadence (every 3 days vs fortnightly). On ads, in-app purchases and device support there is nothing between them.
