# 百度文库 vs 练声

The clearest difference is ads: 练声 at none against 百度文库's shown. 练声 also leads on rating (5.0 vs 4.6). 百度文库's advantage is ratings volume (1.4K vs 5). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. 百度文库 sells 17 in-app purchases, starting at $1.99 per month and 练声 sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

练声 holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: 百度文库 has 1.4K ratings behind it against 5, so its average is the more settled of the two.

Both ship on a similar rhythm, roughly every 2 weeks. The most recent releases landed on September 29, 2026 and June 7, 2026 respectively.
