Verdict
The clearest difference is price: HVACsim at Free against BrainMate's $0.99. HVACsim also leads on ratings volume (13 vs 2) and iOS requirement (13.4 vs 17.5). BrainMate's advantage is rating (5.0 vs 2.2) and in-app purchases (none vs 1). On update cadence, ads and device support there is nothing between them.
