# 百词斩 vs ClassIn

The clearest difference is rating: 百词斩 at 4.8 against ClassIn's 3.6. 百词斩 also leads on review sentiment (76% vs 51%) and ratings volume (9K vs 1K). ClassIn's advantage is ads (none vs shown). 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 ClassIn sells 11 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

百词斩 holds the better App Store score, 4.8 against 3.6. That said, the two scores are not equally well evidenced: 百词斩 has 9K ratings behind it against 1K, 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 51% of ClassIn's.

百词斩 ships an update fortnightly, ClassIn every 11 days. The most recent releases landed on September 25, 2026 and September 23, 2026 respectively.
