# Vaia vs StudyOS

The clearest difference is ratings volume: Vaia at 1.5K against StudyOS's 66. StudyOS's advantage is rating (4.9 vs 4.7). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Vaia sells 15 in-app purchases, starting at $2.99 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: Vaia has 1.5K ratings behind it against 66, so its average is the more settled of the two.

Vaia ships an update weekly, StudyOS every 9 days. The most recent releases landed on October 17, 2026 and October 3, 2026 respectively.
