Verdict
The clearest difference is ads: Katimini at none against Grammatisch's shown. Katimini also leads on review sentiment (100% vs 72%) and rating (5.0 vs 4.7). Grammatisch's advantage is ratings volume (723 vs 2). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Grammatisch sells 5 in-app purchases, starting at $7.99 per 7 days and Katimini sells 2 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.
Katimini holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Grammatisch has 723 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 72% of Grammatisch's written reviews are positive against 100% of Katimini's.
Grammatisch ships an update every 8 days, Katimini weekly. The most recent releases landed on November 11, 2026 and October 30, 2026 respectively.
