# StudyOS vs StudyNotes AI

The clearest difference is ratings volume: StudyOS at 66 against StudyNotes AI's 1. StudyOS also leads on update cadence (every 9 days vs every 6 weeks). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. StudyOS sells 4 in-app purchases, starting at $4.99 per 7 days and StudyNotes AI sells 3 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for StudyOS against 5.0 for StudyNotes AI. That said, the two scores are not equally well evidenced: StudyOS has 66 ratings behind it against 1, so its average is the more settled of the two.

StudyOS ships an update every 9 days, StudyNotes AI every 6 weeks. The most recent releases landed on October 3, 2026 and October 2, 2026 respectively.
