Verdict

The call

The clearest difference is rating: 百度文库 at 4.6 against 掌阅课外书's 2.0. 百度文库 also leads on ratings volume (1.4K vs 2). 掌阅课外书's advantage is ads (none vs shown) and iOS requirement (11.0 vs 13.0). On price, review sentiment, update cadence and in-app purchases there is nothing between them.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. 百度文库 sells 10 in-app purchases, starting at $1.99 per month and 掌阅课外书 sells 10 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

百度文库 holds the better App Store score, 4.6 against 2.0. That said, the two scores are not equally well evidenced: 百度文库 has 1.4K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 76% of 百度文库's written reviews are positive against 82% of 掌阅课外书's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 2 weeks. The most recent releases landed on November 8, 2026 and November 2, 2026 respectively.
