# Lathe Calculator vs Algorithm Heroes

Lathe Calculator and Algorithm Heroes 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. Lathe Calculator sells 1 one-off in-app purchase and Algorithm Heroes sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Lathe Calculator ships an update weekly, Algorithm Heroes every 4 days. The most recent releases landed on October 18, 2026 and October 5, 2026 respectively.
