Verdict

The call

The clearest difference is in-app purchases: ieRcalc at none against Geek Math's 1. ieRcalc also leads on ads (none vs shown) and update cadence (every 4 days vs every 10 months). Geek Math's advantage is iOS requirement (12.0 vs 15.1). On price and device support there is nothing between them.
