# Psychology vs Communication Test

The clearest difference is in-app purchases: Communication Test at none against Psychology's 1. Psychology's advantage is update cadence (every 10 days vs every 4 months). On price, ads, device support and iOS requirement there is nothing between them.

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

Psychology ships an update every 10 days, Communication Test every 4 months. The most recent releases landed on October 5, 2026 and October 27, 2026 respectively.
