# 403 vs Answer Book

The clearest difference is in-app purchases: 403 at none against Answer Book's 1. Answer Book's advantage is device support. On price and iOS requirement there is nothing between them.

Both are free to download. Answer Book sells 1 one-off in-app purchase. 403 asks for nothing beyond the download.
