# VirtualKim vs Turing Machine

The clearest difference is in-app purchases: Turing Machine at none against VirtualKim's 1. Turing Machine also leads on rating (5.0 vs 4.8) and iOS requirement (15.2 vs 17.0). VirtualKim's advantage is ratings volume (29 vs 2). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. VirtualKim sells 1 one-off in-app purchase. Turing Machine asks for nothing beyond the download.

Turing Machine holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: VirtualKim has 29 ratings behind it against 2, so its average is the more settled of the two.

VirtualKim ships an update weekly, Turing Machine every 5 days. The most recent releases landed on October 9, 2026 and October 1, 2026 respectively.
