# Study Note vs OS One

The clearest difference is rating: OS One at 5.0 against Study Note's 4.6. Study Note's advantage is ratings volume (24 vs 1) and iOS requirement (16.0 vs 26.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Study Note sells 3 in-app purchases, starting at $9.99 per 7 days and OS One sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

OS One holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Study Note has 24 ratings behind it against 1, so its average is the more settled of the two.

Study Note ships an update weekly, OS One every 4 days. The most recent releases landed on October 14, 2026 and September 30, 2026 respectively.
