Verdict
The clearest difference is in-app purchases: FractionAndProbability at none against Fast Math's 6. FractionAndProbability also leads on update cadence (every 2 days vs every 4 months). Fast Math's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
