# Study Lock vs StudyIn

The clearest difference is rating: StudyIn at 5.0 against Study Lock's 4.8. Study Lock's advantage is ratings volume (10 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Study Lock sells 2 in-app purchases, starting at $5.99 per month and StudyIn sells 6 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

StudyIn holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Study Lock has 10 ratings behind it against 1, so its average is the more settled of the two.

Study Lock ships an update every 10 days, StudyIn every 2 weeks. Both last shipped on October 24, 2026.
