# Scrum Master Exam Prep vs SimStack Lite

Scrum Master Exam Prep and SimStack Lite are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. Scrum Master Exam Prep sells 1 one-off in-app purchase and SimStack Lite sells 2 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on November 4, 2026 and November 5, 2026 respectively.
