# WeightPix vs Slim

The clearest difference is iOS requirement: WeightPix at 15.1 against Slim's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. WeightPix sells 2 in-app purchases, starting at $6.99 per month and Slim sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
