Verdict
The clearest difference is in-app purchases: SandyCal at none against CompisCalculator Pro's 1. SandyCal also leads on update cadence (every 2 days vs every 3 weeks). CompisCalculator Pro's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 26.2). On price and ads there is nothing between them.
