# 클래스카드 vs 시원스쿨 B2B

The clearest difference is rating: 시원스쿨 B2B at 4.8 against 클래스카드's 4.3. 클래스카드's advantage is in-app purchases (none vs 1) and update cadence (every 4 days vs every 6 weeks). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. 시원스쿨 B2B sells 1 one-off in-app purchase. 클래스카드 asks for nothing beyond the download.

시원스쿨 B2B holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: 클래스카드 has 207 ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 70% of 클래스카드's written reviews are positive against 64% of 시원스쿨 B2B'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, 시원스쿨 B2B every 6 weeks. The most recent releases landed on September 28, 2026 and September 29, 2026 respectively.
