# 启音在线 vs CFA考试题库

The clearest difference is update cadence: 启音在线 at every 6 weeks against CFA考试题库's every 5 months. CFA考试题库's advantage is iOS requirement (9.0 vs 12.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 启音在线 sells 10 one-off in-app purchases and CFA考试题库 sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

启音在线 ships an update every 6 weeks, CFA考试题库 every 5 months. The most recent releases landed on October 15, 2026 and October 9, 2026 respectively.
