# 易错词库 vs 语文快乐听写

The clearest difference is ads: 易错词库 at none against 语文快乐听写's shown. 易错词库 also leads on update cadence (every 11 days vs every 3 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. 易错词库 sells 1 one-off in-app purchase and 语文快乐听写 sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

易错词库 ships an update every 11 days, 语文快乐听写 every 3 weeks. Both last shipped on November 3, 2026.
