# 粉笔 vs 51论文查重

The clearest difference is ratings volume: 粉笔 at 394 against 51论文查重's 2. 粉笔 also leads on update cadence (weekly vs fortnightly). 51论文查重's advantage is rating (5.0 vs 4.7) and iOS requirement (11.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. 粉笔 sells 103 one-off in-app purchases and 51论文查重 sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

51论文查重 holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: 粉笔 has 394 ratings behind it against 2, so its average is the more settled of the two.

粉笔 ships an update weekly, 51论文查重 fortnightly. The most recent releases landed on September 29, 2026 and September 8, 2026 respectively.
