# Kiwi AI vs StudyOS

The clearest difference is ratings volume: Kiwi AI at 563 against StudyOS's 91. On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Kiwi AI sells 10 in-app purchases, starting at $8.99 per month and StudyOS sells 4 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

StudyOS holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Kiwi AI has 563 ratings behind it against 91, so its average is the more settled of the two.
