# 芥末留学 vs MOJiTest

The clearest difference is review sentiment: 芥末留学 at 100% against MOJiTest's 50%. 芥末留学 also leads on rating (5.0 vs 4.5) and iOS requirement (9.0 vs 13). MOJiTest's advantage is ratings volume (458 vs 4) and update cadence (every 9 days vs monthly). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 芥末留学 sells 6 one-off in-app purchases and MOJiTest sells 15 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

芥末留学 holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: MOJiTest has 458 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 100% of 芥末留学's written reviews are positive against 50% of MOJiTest's.

芥末留学 ships an update monthly, MOJiTest every 9 days. The most recent releases landed on October 3, 2026 and October 18, 2026 respectively.
