# AI Diary vs E

The clearest difference is in-app purchases: AI Diary at none against E's 1. E's advantage is ads (none vs shown) and device support (3 vs 1). On price there is nothing between them.

Both are free to download. E sells 1 in-app purchase, starting at $2.99 per month. AI Diary asks for nothing beyond the download.
