# Plumber Prep vs Weko Pro

The clearest difference is device support: Weko Pro at 3 against Plumber Prep's 1. Weko Pro also leads on iOS requirement (15.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Plumber Prep sells 2 in-app purchases, starting at $6.99 per month and Weko Pro sells 2 in-app purchases, starting at $199.00 per month. Whichever you choose, the download price is not the number that matters.
