# 日语语法酷 vs MOJiTest

The clearest difference is rating: MOJiTest at 4.5 against 日语语法酷's 4.0. MOJiTest also leads on update cadence (every 9 days vs every 5 months) and ratings volume (456 vs 8). 日语语法酷's advantage is in-app purchases (none vs 17) and review sentiment (71% vs 50%). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. MOJiTest sells 15 one-off in-app purchases. 日语语法酷 asks for nothing beyond the download.

MOJiTest holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: MOJiTest has 456 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 71% of 日语语法酷's written reviews are positive against 50% of MOJiTest's, so the app with the better star average is not the one people write more warmly about.

日语语法酷 ships an update every 5 months, MOJiTest every 9 days. The most recent releases landed on July 17, 2026 and September 23, 2026 respectively.
