# 预约计划 vs 记事本

The clearest difference is in-app purchases: 预约计划 at none against 记事本's 3. 记事本's advantage is device support. On price and iOS requirement there is nothing between them.

Both are free to download. 记事本 sells 3 in-app purchases, starting at $0.99 per month. 预约计划 asks for nothing beyond the download.
