# Auto Delete vs 電子黒板

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

Both are free to download. Auto Delete sells 1 in-app purchase, starting at $2.99 per month. 電子黒板 asks for nothing beyond the download.
