Do you struggle to hear and understand numbers in your new language? Whether it is numbers, prices, dates, or time… the ability to comprehend spoken numbers is often the most overlooked, but critical part of communicating in any language. If this describes you then download knūmero for free! What is knūmero? knūmero is a language learning app designed to help all language learners (new, intermediate, or advanced) practice listening to and understanding numbers in their new language. Why use knūmero? Regardless of what language you speak or the language you are learning, numbers are everywhere! Whether it is your first day learning Spanish, paying for a baguette in France, or taking a taxi in Tokyo, hearing and comprehending numbers in a new language is challenging for language learners and travelers around the world. How knūmero works… With knūmero you can create unlimited and fully customizable audio lessons that play numbers in both your new and native languages. New language learners can start with easy numbers (0 – 9), played slowly, and in order. Intermediate and advanced language learners can practice more challenging numbers (1,000 – 10,000) and adjust difficulty by using smaller multiples and faster speed. knūmero can play numbers in your new language two times for improved retention while allowing you to repeat any number as many times as you like. Multiples are the perfect way to adjust skill level. For any number range in knūmero, you can practice easier numbers (10,000… 11,000) or more difficult numbers (10,150… 11,745). You can also reverse the language order in knūmero. Listen to numbers in your new language first, then practice listening to numbers in your native language and translate them. Practice numbers between 12 languages… knūmero supports Spanish (Latin America and Spain), French, Italian, Portuguese, English, German, Russian, Chinese (Mandarin), Japanese, Korean, Hindi, and Arabic. With knūmero you can practice between any supported languages. A French student can practice numbers in Portuguese while a German engineer can practice numbers in Mandarin. With just a few minutes of practice every day, your ability to hear and comprehend numbers can rapidly improve with knūmero! Download the app and get started today!

Verdict
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.
