# Mechanical Pendulums vs Wittgenstein

The clearest difference is in-app purchases: Mechanical Pendulums at none against Wittgenstein's 1. Mechanical Pendulums also leads on iOS requirement (15.0 vs 17.6). Wittgenstein's advantage is device support. On price there is nothing between them.

Both are free to download. Wittgenstein sells 1 one-off in-app purchase. Mechanical Pendulums asks for nothing beyond the download.
