# Turing Machine Simulator vs ARURAKU

The clearest difference is price: ARURAKU at Free against Turing Machine Simulator's $2.99. ARURAKU also leads on update cadence (every 2 months vs every 16 months). Turing Machine Simulator's advantage is ads (none vs shown) and iOS requirement (15.0 vs 17.0). On in-app purchases and device support there is nothing between them.

ARURAKU 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 Simulator ships an update every 16 months, ARURAKU every 2 months. Both last shipped on October 7, 2026.
