# 作业帮口算 vs 数学口算HD

The clearest difference is update cadence: 作业帮口算 at fortnightly against 数学口算HD's every 6 months. 作业帮口算 also leads on ratings volume (228 vs 4) and review sentiment (86% vs 75%). 数学口算HD's advantage is rating (5.0 vs 4.7) and iOS requirement (9.0 vs 13.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. 作业帮口算 sells 8 in-app purchases, starting at $2.99 per month and 数学口算HD sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

数学口算HD holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: 作业帮口算 has 228 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 86% of 作业帮口算's written reviews are positive against 75% of 数学口算HD's, so the app with the better star average is not the one people write more warmly about.

作业帮口算 ships an update fortnightly, 数学口算HD every 6 months. The most recent releases landed on November 7, 2026 and November 3, 2026 respectively.
