# SchemaSim vs MCTS

SchemaSim and MCTS 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. SchemaSim sells 2 in-app purchases, starting at $9.99 per month and MCTS sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

SchemaSim ships an update every 2 weeks, MCTS every 3 weeks. Both last shipped on October 24, 2026.
