# Poolistry vs Passwords PSW

The clearest difference is ads: Passwords PSW at none against Poolistry's shown. Poolistry's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price and in-app purchases there is nothing between them.

Both are free to download. Poolistry sells 3 in-app purchases, starting at $1.99 per month and Passwords PSW sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
