# Attention vs 单词速记

The clearest difference is ads: 单词速记 at none against Attention's shown. 单词速记 also leads on update cadence (every 3 weeks vs every 9 months). Attention's advantage is iOS requirement (12.0 vs 15.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Attention sells 1 one-off in-app purchase and 单词速记 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Attention ships an update every 9 months, 单词速记 every 3 weeks. The most recent releases landed on October 26, 2026 and October 30, 2026 respectively.
