# Psychology vs Tabu

The clearest difference is in-app purchases: Tabu at none against Psychology's 1. Tabu also leads on iOS requirement (13.1 vs 15.0). Psychology's advantage is device support. On price there is nothing between them.

Both are free to download. Psychology sells 1 one-off in-app purchase. Tabu asks for nothing beyond the download.
