# 二级建造师 vs 二建题库

The clearest difference is update cadence: 二级建造师 at every 6 weeks against 二建题库's every 3 months. 二建题库's advantage is iOS requirement (9.0 vs 15.6). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 二级建造师 sells 3 one-off in-app purchases and 二建题库 sells 4 in-app purchases, starting at $0.99 per 3 months. Whichever you choose, the download price is not the number that matters.

二级建造师 ships an update every 6 weeks, 二建题库 every 3 months. The most recent releases landed on July 17, 2026 and September 18, 2026 respectively.
