# 15 vs BookNotes

The clearest difference is ads: BookNotes at none against 15's shown. 15's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 18.0). On price and in-app purchases there is nothing between them.

Both are free to download. 15 sells 2 in-app purchases, starting at $4.99 per 7 days and BookNotes sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
