# Graphia vs SignAuthAI

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

Both are free to download. Graphia sells 5 in-app purchases, starting at $3.99 per 7 days and SignAuthAI sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
