# Turing Machine Simulator vs Equation

The clearest difference is update cadence: Equation at monthly against Turing Machine Simulator's every 19 months. Equation also leads on price ($1.99 vs $2.99). Turing Machine Simulator's advantage is iOS requirement (12.0 vs 15.1). On ads, in-app purchases and device support there is nothing between them.

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

Turing Machine Simulator ships an update every 19 months, Equation monthly. The most recent releases landed on September 20, 2026 and September 24, 2026 respectively.
