# 내공스터디 vs Class5 (클래스5)

The clearest difference is rating: 내공스터디 at 5.0 against Class5 (클래스5)'s 2.1. Class5 (클래스5)'s advantage is review sentiment (86% vs 75%) and ratings volume (7 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

내공스터디 holds the better App Store score, 5.0 against 2.1. That said, the two scores are not equally well evidenced: Class5 (클래스5) has 7 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 75% of 내공스터디's written reviews are positive against 86% of Class5 (클래스5)'s, so the app with the better star average is not the one people write more warmly about.

내공스터디 ships an update every 6 days, Class5 (클래스5) every 11 days. Both last shipped on November 3, 2026.
