Verdict
The clearest difference is update cadence: QTc at every 4 months against Thopaz+ Simulator's every 85 months. QTc also leads on ratings volume (51 vs 1). Thopaz+ Simulator's advantage is rating (5.0 vs 4.7) and iOS requirement (12.0 vs 18.0). On price, ads, in-app purchases and monetization model there is nothing between them.
