Verdict
The clearest difference is in-app purchases: Monte Carlo Pi at none against Physics Constants Library's 1. Monte Carlo Pi also leads on ads (none vs shown) and iOS requirement (15.0 vs 18.4). Physics Constants Library's advantage is update cadence (every 7 months vs every 22 months). On price and device support there is nothing between them.
