# Grammatisch vs knūmero

The clearest difference is ads: knūmero at none against Grammatisch's shown. knūmero also leads on review sentiment (100% vs 72%) and iOS requirement (8.0 vs 18.0). Grammatisch's advantage is rating (4.7 vs 4.3) and ratings volume (723 vs 7). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Grammatisch sells 5 in-app purchases, starting at $7.99 per 7 days and knūmero sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Grammatisch holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Grammatisch has 723 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 72% of Grammatisch's written reviews are positive against 100% of knūmero's, so the app with the better star average is not the one people write more warmly about.

Grammatisch ships an update every 9 days, knūmero every 2 months. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
