Verdict
The clearest difference is in-app purchases: ArrowMetrics at none against Foc Calculator's 1. ArrowMetrics also leads on ads (none vs shown). Foc Calculator's advantage is update cadence (every 6 days vs every 2 months). On price, device support and iOS requirement there is nothing between them.
