# 百度文库 vs 古文岛

The clearest difference is ads: 古文岛 at none against 百度文库's shown. 古文岛 also leads on review sentiment (85% vs 76%) and device support (4 vs 2). 百度文库's advantage is ratings volume (1.4K vs 128) and iOS requirement (13.0 vs 15.5). On price, rating, update cadence and in-app purchases 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 古文岛 sells 10 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for 百度文库 against 4.6 for 古文岛. That said, the two scores are not equally well evidenced: 百度文库 has 1.4K ratings behind it against 128, so its average is the more settled of the two. Written reviews are what separate them: 76% of 百度文库's written reviews are positive against 85% of 古文岛's.

Both ship on a similar rhythm, roughly every 2 weeks. The most recent releases landed on November 9, 2026 and November 7, 2026 respectively.
