# 百度文库 vs 蝶变高考

The clearest difference is ads: 蝶变高考 at none against 百度文库's shown. 百度文库's advantage is update cadence (fortnightly vs every 6 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. 百度文库 sells 10 in-app purchases, starting at $1.99 per month and 蝶变高考 sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

百度文库 ships an update fortnightly, 蝶变高考 every 6 weeks. The most recent releases landed on November 11, 2026 and November 2, 2026 respectively.
