# Turing Machine Simulator vs Multitape Turing Machine

The clearest difference is price: Multitape Turing Machine at Free against Turing Machine Simulator's $2.99. Multitape Turing Machine also leads on rating (5.0 vs 4.8) and update cadence (every 8 months vs every 19 months). Turing Machine Simulator's advantage is ratings volume (4 vs 1) and iOS requirement (12.0 vs 16.0). On review sentiment, ads, in-app purchases and device support there is nothing between them.

Multitape 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.

Multitape Turing Machine holds the better App Store score, 5.0 against 4.8. Both are backed by a comparable volume of ratings — 4 and 1 respectively. Written reviews split almost evenly too, at 100% and 100% positive.

Turing Machine Simulator ships an update every 19 months, Multitape Turing Machine every 8 months. The most recent releases landed on August 14, 2026 and June 1, 2026 respectively.
