# Electronic Calculator vs Read Offline Web

The clearest difference is in-app purchases: Electronic Calculator at none against Read Offline Web's 1. Read Offline Web's advantage is iOS requirement (15.0 vs 17.6). On price, ads and device support there is nothing between them.

Both are free to download. Read Offline Web sells 1 one-off in-app purchase. Electronic Calculator asks for nothing beyond the download.
