# 务实 vs Multitape Turing Machine

The clearest difference is in-app purchases: Multitape Turing Machine at none against 务实's 4. 务实's advantage is update cadence (monthly vs every 8 months) and iOS requirement (9.0 vs 16.0). On price, ads and device support there is nothing between them.

Both are free to download. 务实 sells 4 one-off in-app purchases. Multitape Turing Machine asks for nothing beyond the download.

务实 ships an update monthly, Multitape Turing Machine every 8 months. The most recent releases landed on September 15, 2026 and June 1, 2026 respectively.
