# Stable Diffusion vs ImageGen

The clearest difference is ratings volume: Stable Diffusion at 54 against ImageGen's 9. ImageGen's advantage is iOS requirement (13.0 vs 16.0). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Stable Diffusion sells 3 in-app purchases, starting at $6.99 per 7 days and ImageGen sells 3 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.2 for Stable Diffusion against 4.1 for ImageGen. That said, the two scores are not equally well evidenced: Stable Diffusion has 54 ratings behind it against 9, so its average is the more settled of the two.
