# 코스모스 vs CLASSUM

The clearest difference is rating: 코스모스 at 4.1 against CLASSUM's 3.8. 코스모스 also leads on ratings volume (301 vs 19). CLASSUM's advantage is review sentiment (63% vs 50%). 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.

코스모스 holds the better App Store score, 4.1 against 3.8. That said, the two scores are not equally well evidenced: 코스모스 has 301 ratings behind it against 19, so its average is the more settled of the two. Written reviews complicate that: 50% of 코스모스's written reviews are positive against 63% of CLASSUM's, so the app with the better star average is not the one people write more warmly about.

코스모스 ships an update weekly, CLASSUM fortnightly. Both last shipped on September 26, 2026.
