# DSA Master vs Classix

DSA Master and Classix 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. DSA Master sells 1 one-off in-app purchase and Classix sells 1 in-app purchase, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly weekly. The most recent releases landed on September 22, 2026 and September 23, 2026 respectively.
