# Turing Machine Simulator vs Another Turing Machine

The clearest difference is update cadence: Another Turing Machine at daily against Turing Machine Simulator's every 16 months. Another Turing Machine also leads on price ($1.99 vs $2.99). Turing Machine Simulator's advantage is iOS requirement (15.0 vs 18.2). On ads, in-app purchases and device support there is nothing between them.

Turing Machine Simulator costs $2.99 and Another Turing Machine $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, Another Turing Machine daily. The most recent releases landed on October 7, 2026 and October 9, 2026 respectively.
