# StudyOS vs StudyFi

The clearest difference is rating: StudyOS at 4.9 against StudyFi's 3.7. StudyOS also leads on ratings volume (66 vs 6). On price, update cadence, 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 StudyFi sells 16 in-app purchases, starting at $11.99 per month. Whichever you choose, the download price is not the number that matters.

StudyOS holds the better App Store score, 4.9 against 3.7. That said, the two scores are not equally well evidenced: StudyOS has 66 ratings behind it against 6, so its average is the more settled of the two.
