The clearest difference is rating: 클래스카드 at 4.2 against 기후행동1.5℃'s 3.7. 클래스카드 also leads on update cadence (every 4 days vs every 2 months) and ratings volume (207 vs 3). 기후행동1.5℃'s advantage is review sentiment (88% vs 70%). On price, ads, in-app purchases and device support there is nothing between them.

클래스카드 holds the better App Store score, 4.2 against 3.7. That said, the two scores are not equally well evidenced: 클래스카드 has 207 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 70% of 클래스카드's written reviews are positive against 88% of 기후행동1.5℃'s, so the app with the better star average is not the one people write more warmly about.

클래스카드 ships an update every 4 days, 기후행동1.5℃ every 2 months. The most recent releases landed on October 15, 2026 and October 17, 2026 respectively.
