# OneBook vs 小词书

The clearest difference is monetization model: 小词书 at free against OneBook's freemium. OneBook's advantage is ratings volume (64 vs 2) and iOS requirement (15.0 vs 17.0). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. OneBook sells 2 in-app purchases, starting at $8.00 per month and 小词书 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for OneBook against 5.0 for 小词书. That said, the two scores are not equally well evidenced: OneBook has 64 ratings behind it against 2, so its average is the more settled of the two.

Both ship on a similar rhythm, roughly weekly. The most recent releases landed on November 8, 2026 and October 30, 2026 respectively.
