# StudyOS vs EinstIA

The clearest difference is rating: StudyOS at 4.9 against EinstIA's 1.0. StudyOS also leads on monetization model (freemium vs subscription) and ratings volume (66 vs 1). EinstIA's advantage is update cadence (every 4 days vs every 9 days) and iOS requirement (15.1 vs 17.1). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. StudyOS sells 4 in-app purchases, starting at $4.99 per 7 days and EinstIA sells 4 in-app purchases, starting at $1.99 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 1.0. 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, EinstIA every 4 days. The most recent releases landed on October 20, 2026 and October 12, 2026 respectively.
