# CodeMath vs Kido

CodeMath and Kido are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. CodeMath sells 1 one-off in-app purchase and Kido sells 3 in-app purchases, starting at $14.99 per year. Whichever you choose, the download price is not the number that matters.

CodeMath ships an update every 2 weeks, Kido every 10 days. Both last shipped on October 24, 2026.
