# Stack vs PixelFlip

The clearest difference is in-app purchases: Stack at none against PixelFlip's 1. Stack also leads on device support (3 vs 1) and iOS requirement (18.0 vs 26.0). On price and ads there is nothing between them.

Both are free to download. PixelFlip sells 1 one-off in-app purchase. Stack asks for nothing beyond the download.
