# Turing Machine Simulator vs Logic

The clearest difference is review sentiment: Turing Machine Simulator at 100% against Logic's 0%. Turing Machine Simulator also leads on price ($2.99 vs $5.99) and iOS requirement (12.0 vs 15.1). Logic's advantage is update cadence (every 5 weeks vs every 19 months). On ads, in-app purchases, monetization model and device support there is nothing between them.

Turing Machine Simulator costs $2.99 and Logic $5.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Turing Machine Simulator ships an update every 19 months, Logic every 5 weeks. The most recent releases landed on September 20, 2026 and September 24, 2026 respectively.
