# PSM I vs Professional Scrum Master II

The clearest difference is update cadence: PSM I at every 6 weeks against Professional Scrum Master II's every 11 months. Professional Scrum Master II's advantage is iOS requirement (10.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. PSM I sells 2 one-off in-app purchases and Professional Scrum Master II sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

PSM I ships an update every 6 weeks, Professional Scrum Master II every 11 months. The most recent releases landed on November 3, 2026 and October 7, 2026 respectively.
