# ClassIn vs 赛优课堂

The clearest difference is review sentiment: ClassIn at 51% against 赛优课堂's 0%. ClassIn also leads on ratings volume (1K vs 1) and iOS requirement (13.0 vs 15.0). 赛优课堂's advantage is rating (5.0 vs 3.6). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. ClassIn sells 13 one-off in-app purchases and 赛优课堂 sells 9 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

赛优课堂 holds the better App Store score, 5.0 against 3.6. That said, the two scores are not equally well evidenced: ClassIn has 1K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 51% of ClassIn's written reviews are positive against 0% of 赛优课堂's, so the app with the better star average is not the one people write more warmly about.

ClassIn ships an update every 11 days, 赛优课堂 every 3 weeks. The most recent releases landed on October 19, 2026 and October 6, 2026 respectively.
