# Math Interactive vs Nihongo Lessons

The clearest difference is update cadence: Nihongo Lessons at every 3 weeks against Math Interactive's every 13 months. Nihongo Lessons also leads on review sentiment (85% vs 58%) and rating (4.8 vs 4.6). Math Interactive's advantage is ratings volume (726 vs 126) and device support (3 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Math Interactive sells 1 one-off in-app purchase and Nihongo Lessons sells 13 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Nihongo Lessons holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Math Interactive has 726 ratings behind it against 126, so its average is the more settled of the two. Written reviews point the same way: 58% of Math Interactive's written reviews are positive against 85% of Nihongo Lessons's.

Math Interactive ships an update every 13 months, Nihongo Lessons every 3 weeks. The most recent releases landed on September 29, 2026 and October 9, 2026 respectively.
