# Turing Machine Simulator vs Geometry

The clearest difference is update cadence: Geometry at monthly against Turing Machine Simulator's every 16 months. Geometry also leads on price ($1.99 vs $2.99). On ads, in-app purchases, device support and iOS requirement there is nothing between them.

Turing Machine Simulator costs $2.99 and Geometry $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Turing Machine Simulator ships an update every 16 months, Geometry monthly. The most recent releases landed on October 23, 2026 and October 12, 2026 respectively.
