# Turing Machine Simulator vs Turing Machine

The clearest difference is price: Turing Machine at Free against Turing Machine Simulator's $2.99. Turing Machine also leads on update cadence (every 5 days vs every 19 months) and rating (5.0 vs 4.8). Turing Machine Simulator's advantage is iOS requirement (12.0 vs 15.2). On ratings volume, ads, in-app purchases and device support there is nothing between them.

Turing Machine is free to download; Turing Machine Simulator costs $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Turing Machine holds the better App Store score, 5.0 against 4.8. Both are backed by a comparable volume of ratings — 4 and 2 respectively.

Turing Machine Simulator ships an update every 19 months, Turing Machine every 5 days. The most recent releases landed on September 20, 2026 and October 1, 2026 respectively.
