# 普通话水平测试 vs 口算批改

The clearest difference is rating: 口算批改 at 5.0 against 普通话水平测试's 3.9. 普通话水平测试's advantage is update cadence (every 3 weeks vs every 3 months) and ratings volume (11 vs 2). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 普通话水平测试 sells 4 in-app purchases, starting at $2.99 per month and 口算批改 sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

口算批改 holds the better App Store score, 5.0 against 3.9. That said, the two scores are not equally well evidenced: 普通话水平测试 has 11 ratings behind it against 2, so its average is the more settled of the two.

普通话水平测试 ships an update every 3 weeks, 口算批改 every 3 months. The most recent releases landed on November 7, 2026 and November 3, 2026 respectively.
