With ReflexNum, you can practice numbers in 9 languages: English, French, Spanish, German, Russian, Italian, Portuguese, Chinese, and Japanese. ReflexNum helps language learners become faster and more confident at understanding spoken numbers. Study Mode Enter any number from zero to billions and instantly see how itβs written in words. With a simple tap, you can listen to the pronunciation to help you master how numbers are spoken in your target language. Listening Challenges Test your skills with timed games designed to improve your listening comprehension speed. How it works: Listen to a random number and type what you hear before time runs out. If you make a mistake, the app provides a correction. You can listen to both the correct number and your entry to compare them. This helps you identify the subtle differences between similar-sounding numbers. Randomized Keypad To further boost your concentration, the keypad buttons can change positions every round in higher levels. This feature is designed to ensure you are truly recognizing the numbers rather than just remembering the layout of the keys. It can help sharpen your focus and build faster mental reflexes. 2-Player Mode Play against a friend on the same screen! Listen closely to the number and type it in.
