# 하이클래스 vs 컴시간알리미

The clearest difference is review sentiment: 하이클래스 at 94% against 컴시간알리미's 61%. 하이클래스 also leads on ratings volume (397 vs 2) and update cadence (weekly vs every 3 weeks). 컴시간알리미's advantage is rating (5.0 vs 4.7). On price, ads, in-app purchases and device support there is nothing between them.

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

컴시간알리미 holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: 하이클래스 has 397 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 94% of 하이클래스's written reviews are positive against 61% of 컴시간알리미's, so the app with the better star average is not the one people write more warmly about.

하이클래스 ships an update weekly, 컴시간알리미 every 3 weeks. Both last shipped on October 30, 2026.
