# TestMax vs Stack

TestMax and Stack 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. TestMax sells 4 in-app purchases, starting at $3.99 per 7 days and Stack sells 2 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.

TestMax ships an update every 2 weeks, Stack every 8 days. The most recent releases landed on September 13, 2026 and September 14, 2026 respectively.
