# 四年级英语下册 vs 测距助手

The clearest difference is in-app purchases: 测距助手 at none against 四年级英语下册's 1. 四年级英语下册's advantage is ads (none vs shown) and iOS requirement (8.0 vs 11.0). On price and device support there is nothing between them.

Both are free to download. 四年级英语下册 sells 1 one-off in-app purchase. 测距助手 asks for nothing beyond the download.
