# Electro Math vs 計算用紙

The clearest difference is in-app purchases: 計算用紙 at none against Electro Math's 1. Electro Math's advantage is ads (none vs shown) and iOS requirement (13.0 vs 16.6). On price and device support there is nothing between them.

Both are free to download. Electro Math sells 1 in-app purchase, starting at $2.99 per month. 計算用紙 asks for nothing beyond the download.
