# 作业帮 vs 口算批改

The clearest difference is rating: 口算批改 at 5.0 against 作业帮's 4.5. 作业帮's advantage is update cadence (every 11 days vs every 3 months) and ratings volume (3.4K vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. 作业帮 sells 17 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 4.5. That said, the two scores are not equally well evidenced: 作业帮 has 3.4K ratings behind it against 2, so its average is the more settled of the two.

作业帮 ships an update every 11 days, 口算批改 every 3 months. The most recent releases landed on October 19, 2026 and September 28, 2026 respectively.
