# DeepEng HD vs 识词本

The clearest difference is in-app purchases: 识词本 at none against DeepEng HD's 1. 识词本 also leads on update cadence (every 2 days vs weekly) and device support (6 vs 3). On price, ads and iOS requirement there is nothing between them.

Both are free to download. DeepEng HD sells 1 one-off in-app purchase. 识词本 asks for nothing beyond the download.

DeepEng HD ships an update weekly, 识词本 every 2 days. Both last shipped on October 9, 2026.
