Verdict
The clearest difference is price: RF Calculators at Free against RF Tools ++'s $1.99. RF Calculators also leads on update cadence (every 4 days vs every 2 weeks) and iOS requirement (12.0 vs 17.0). RF Tools ++'s advantage is ads (none vs shown). On in-app purchases and device support there is nothing between them.
