Multitape Turing Machine Simulator. A Turing machine is a mathematical model of computation describing an abstract machine, that manipulates symbols on a strip of tape according to a table of rules. Despite the model's simplicity, it is capable of implementing any computer algorithm. The machine operates on a memory tape divided into cells, each of which can hold a single symbol drawn from symbols from the alphabet of the machine. It has a "head" that, at any point in the machine's operation, is positioned over one of these cells, and a "state" selected from a set of states. At each step of its operation, the head reads the symbol in its cell. Then, based on the symbol and the machine's own present state, the machine writes a symbol into the same cell, and moves the head one step to the left or the right, or halts the computation. The choice of which replacement symbol to write and which direction to move is based on a table that specifies what to do for each combination of the current state and the symbol that is read.

Verdict
The clearest difference is review sentiment: Multitape Turing Machine at 100% against Little Man Computer's 50%. Multitape Turing Machine also leads on rating (5.0 vs 4.3) and update cadence (every 8 months vs every 45 months). Little Man Computer's advantage is ratings volume (6 vs 1) and iOS requirement (14.0 vs 16.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. 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 4.3. That said, the two scores are not equally well evidenced: Little Man Computer has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 50% of Little Man Computer's written reviews are positive against 100% of Multitape Turing Machine's.
Little Man Computer ships an update every 45 months, Multitape Turing Machine every 8 months. The most recent releases landed on October 24, 2026 and October 10, 2026 respectively.
