Verdict
The clearest difference is price: PleiSolar at Free against KNX Pro Tester's $17.99. PleiSolar also leads on iOS requirement (12.0 vs 26.4). KNX Pro Tester's advantage is update cadence (every 2 days vs every 8 months). On ads, in-app purchases and device support there is nothing between them.
