Verdict
The clearest difference is in-app purchases: A3S at none against Mental Math Kingdom's 1. A3S also leads on device support (3 vs 1) and iOS requirement (13.0 vs 17.0). Mental Math Kingdom's advantage is update cadence (daily vs every 2 weeks). On price and ads there is nothing between them.
