# Turing Machine vs Logic

The clearest difference is rating: Turing Machine at 5.0 against Logic's 3.3. Turing Machine also leads on ads (none vs shown) and update cadence (every 5 days vs every 5 weeks). Logic's advantage is ratings volume (6 vs 2). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Turing Machine holds the better App Store score, 5.0 against 3.3. Both are backed by a comparable volume of ratings — 2 and 6 respectively.

Turing Machine ships an update every 5 days, Logic every 5 weeks. The most recent releases landed on October 1, 2026 and October 12, 2026 respectively.
