# 注意力方块 vs 记忆training

The clearest difference is in-app purchases: 记忆training at none against 注意力方块's 1. 注意力方块's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 7 months). On price and device support there is nothing between them.

Both are free to download. 注意力方块 sells 1 one-off in-app purchase. 记忆training asks for nothing beyond the download.

注意力方块 ships an update every 3 weeks, 记忆training every 7 months. The most recent releases landed on September 14, 2026 and October 1, 2026 respectively.
