# LeetCode vs Discrete Math

LeetCode and Discrete Math 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. LeetCode sells 2 in-app purchases, starting at $35.00 per month and Discrete Math sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

LeetCode ships an update fortnightly, Discrete Math every 3 weeks. The most recent releases landed on October 26, 2026 and October 25, 2026 respectively.
