Verdict

The call

The clearest difference is rating: GraphMath at 4.8 against Polar and Cartesian Converter's 3.0. GraphMath also leads on ads (none vs shown) and update cadence (fortnightly vs every 6 months). Polar and Cartesian Converter's advantage is iOS requirement (13.0 vs 15.6). On price, in-app purchases and device support there is nothing between them.
