# 作业帮 vs 生物圈

The clearest difference is rating: 作业帮 at 4.5 against 生物圈's 3.0. 作业帮 also leads on ratings volume (3.4K vs 2) and update cadence (every 11 days vs monthly). 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 生物圈 sells 8 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

作业帮 holds the better App Store score, 4.5 against 3.0. 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, 生物圈 monthly. The most recent releases landed on October 28, 2026 and October 10, 2026 respectively.
