Verdict
The clearest difference is in-app purchases: DriveClass at none against Thermodynamic Cycles's 4. DriveClass also leads on update cadence (every 11 days vs every 3 months). Thermodynamic Cycles's advantage is device support (4 vs 1) and iOS requirement (15.0 vs 18). On price and ads there is nothing between them.
