# Stackd vs Study Log

The clearest difference is ads: Stackd at none against Study Log's shown. On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Stackd sells 1 one-off in-app purchase and Study Log sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
