# Prisma vs Barklog

The clearest difference is ads: Barklog at none against Prisma's shown. Prisma's advantage is iOS requirement (15.1 vs 17.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Prisma sells 1 in-app purchase, starting at $14.99 per year and Barklog sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
