Verdict
The clearest difference is in-app purchases: SmartCal at none against Calculator's 4. SmartCal also leads on ads (none vs shown) and update cadence (every 3 weeks vs every 6 weeks). Calculator's advantage is iOS requirement (13.0 vs 26.2). On price and device support there is nothing between them.
