# 车工题库 vs 成语典藏

The clearest difference is update cadence: 成语典藏 at every 2 weeks against 车工题库's every 5 months. 车工题库's advantage is iOS requirement (12.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 车工题库 sells 10 one-off in-app purchases and 成语典藏 sells 3 in-app purchases, starting at $4.99 per 3 months. Whichever you choose, the download price is not the number that matters.

车工题库 ships an update every 5 months, 成语典藏 every 2 weeks. The most recent releases landed on October 7, 2026 and October 24, 2026 respectively.
