# Simple Memo vs Stack

The clearest difference is in-app purchases: Stack at none against Simple Memo's 1. Stack also leads on ads (none vs shown). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Simple Memo sells 1 one-off in-app purchase. Stack asks for nothing beyond the download.
