# 一年级上册语文 vs 三信通

The clearest difference is in-app purchases: 三信通 at none against 一年级上册语文's 1. 三信通 also leads on ads (none vs shown). 一年级上册语文's advantage is iOS requirement (8.0 vs 12.0). On price and device support there is nothing between them.

Both are free to download. 一年级上册语文 sells 1 one-off in-app purchase. 三信通 asks for nothing beyond the download.
