# PepstackAI vs InFlight

The clearest difference is iOS requirement: PepstackAI at 15.0 against InFlight's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. PepstackAI sells 2 in-app purchases, starting at $4.99 per month and InFlight sells 4 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
