Verdict
The clearest difference is in-app purchases: Multinomial at none against Probability Sim's 2. Multinomial also leads on ads (none vs shown). Probability Sim's advantage is update cadence (every 10 months vs every 47 months) and iOS requirement (15.0 vs 18.6). On price and device support there is nothing between them.
