iAltair vs Turing Machine
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
iAltair
Experience vintage computing with a simulation of the MITS Altair 8800. Explore old software like CP/M 2 and run programs such as Eliza using built-in BASIC. This self-contained system offers a unique glimpse into early computing history.
- MITS Altair 8800 simulation
- CP/M 2 operating system support
- Built-in BASIC interpreter
- Run Eliza program
- Self-contained system

iAltair pretends to be a MITS Altair 8800 computer. It allows you to get the feeling of really old software such as the CP/M 2 operating system. The system is fully self contained and does not allow you to remotely add any code but you can try out Basic to run Eliza.
Turing Machine
This application allows users to write and execute algorithms on a Turing machine. It is designed to help engineering students in higher education practice and verify their work with algorithms.
- Write algorithms
- Execute algorithms
- Verify algorithm work
- Turing machine simulation
- Educational tool for engineering students

Verdict
The clearest difference is update cadence: Turing Machine at every 5 days against iAltair's every 11 months. Turing Machine also leads on rating (5.0 vs 4.8). iAltair's advantage is ratings volume (21 vs 2). 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.
Turing Machine holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: iAltair has 21 ratings behind it against 2, so its average is the more settled of the two.
iAltair ships an update every 11 months, Turing Machine every 5 days. The most recent releases landed on September 27, 2026 and October 1, 2026 respectively.
