# 考试星 vs 错题本

The clearest difference is rating: 考试星 at 5.0 against 错题本's 4.2. 考试星 also leads on in-app purchases (none vs 2) and update cadence (monthly vs every 2 months). 错题本's advantage is ratings volume (5 vs 1). On price, ads and device support there is nothing between them.

Both are free to download. 错题本 sells 2 in-app purchases, starting at $1.99 per month. 考试星 asks for nothing beyond the download.

考试星 holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: 错题本 has 5 ratings behind it against 1, so its average is the more settled of the two.

考试星 ships an update monthly, 错题本 every 2 months. Both last shipped on November 3, 2026.
