# 速算トレイン vs 電験三種 過去問

The clearest difference is in-app purchases: 速算トレイン at none against 電験三種 過去問's 1. 速算トレイン also leads on iOS requirement (11.0 vs 17.0). 電験三種 過去問's advantage is ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. 電験三種 過去問 sells 1 one-off in-app purchase. 速算トレイン asks for nothing beyond the download.
