# Glin AI vs Prepd

The clearest difference is iOS requirement: Prepd at 13.0 against Glin AI's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Glin AI sells 4 in-app purchases, starting at $8.99 per month and Prepd sells 5 in-app purchases, starting at $39.99 per month. Whichever you choose, the download price is not the number that matters.
