Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
GraphMath holds the better App Store score, 4.8 against 3.0. That said, the two scores are not equally well evidenced: GraphMath has 15 ratings behind it against 1, so its average is the more settled of the two.
Polar and Cartesian Converter ships an update every 6 months, GraphMath fortnightly. The most recent releases landed on September 30, 2026 and October 22, 2026 respectively.
