# 百词斩 vs 安全员练题狗

The clearest difference is ads: 安全员练题狗 at none against 百词斩's shown. 安全员练题狗 also leads on monetization model (free vs free with in-app purchases) and review sentiment (90% vs 76%). 百词斩's advantage is update cadence (fortnightly vs every 6 months) and ratings volume (9K vs 1). On price, in-app purchases and device support there is nothing between them.

Both are free to download. 百词斩 sells 36 in-app purchases, starting at $2.99 per month and 安全员练题狗 sells 9 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

安全员练题狗 holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: 百词斩 has 9K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 76% of 百词斩's written reviews are positive against 90% of 安全员练题狗's.

百词斩 ships an update fortnightly, 安全员练题狗 every 6 months. The most recent releases landed on October 16, 2026 and October 14, 2026 respectively.
