# Prisma vs Game Tracker & Backlog

The clearest difference is ads: Game Tracker & Backlog at none against Prisma's shown. Prisma's advantage is device support (3 vs 1) and iOS requirement (15.1 vs 26.4). On price and in-app purchases there is nothing between them.

Both are free to download. Prisma sells 1 in-app purchase, starting at $14.99 per year and Game Tracker & Backlog sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
