# 试题库 vs 特种作业考试

The clearest difference is in-app purchases: 试题库 at none against 特种作业考试's 3. 试题库 also leads on update cadence (every 3 months vs every 27 months). 特种作业考试's advantage is device support (3 vs 1) and iOS requirement (12.0 vs 17). On price and ads there is nothing between them.

Both are free to download. 特种作业考试 sells 3 one-off in-app purchases. 试题库 asks for nothing beyond the download.

试题库 ships an update every 3 months, 特种作业考试 every 27 months. The most recent releases landed on September 13, 2026 and September 16, 2026 respectively.
