Verdict
The clearest difference is in-app purchases: Queue Swap at none against Calculator Pro's 2. Queue Swap also leads on ads (none vs shown) and iOS requirement (16.0 vs 18.5). Calculator Pro's advantage is update cadence (every 2 weeks vs every 5 weeks). On price and device support there is nothing between them.
