# StudyOS vs Algor

The clearest difference is ratings volume: StudyOS at 66 against Algor's 1. Algor's advantage is iOS requirement (15.0 vs 17.1). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. StudyOS sells 4 in-app purchases, starting at $4.99 per 7 days and Algor sells 4 in-app purchases, starting at $9.99 per month. 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 Algor. 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.
