# 小词书 vs 死磕背单词

The clearest difference is monetization model: 小词书 at free against 死磕背单词's freemium. 死磕背单词's advantage is update cadence (every 2 days vs weekly) and iOS requirement (15.5 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 小词书 sells 1 one-off in-app purchase and 死磕背单词 sells 4 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

小词书 ships an update weekly, 死磕背单词 every 2 days. The most recent releases landed on October 30, 2026 and November 7, 2026 respectively.
