# 百词斩 vs 4D书城

The clearest difference is rating: 百词斩 at 4.8 against 4D书城's 3.7. 百词斩 also leads on ratings volume (9K vs 10) and review sentiment (76% vs 57%). 4D书城's advantage is ads (none vs shown) and iOS requirement (8.0 vs 13.0). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. 百词斩 sells 36 in-app purchases, starting at $2.99 per month and 4D书城 sells 10 in-app purchases, starting at $2.49 per month. Whichever you choose, the download price is not the number that matters.

百词斩 holds the better App Store score, 4.8 against 3.7. That said, the two scores are not equally well evidenced: 百词斩 has 9K ratings behind it against 10, so its average is the more settled of the two. Written reviews point the same way: 76% of 百词斩's written reviews are positive against 57% of 4D书城's.

百词斩 ships an update fortnightly, 4D书城 every 4 weeks. The most recent releases landed on October 20, 2026 and October 10, 2026 respectively.
