This page is designed to help you find out whether Countfu is good and if it is the right choice for you.
Chinese learners hit the same wall in real conversation. You know the words, but a price, a phone number, or a date goes past at native speed and you are still converting when the speaker has moved on. Part of it is structural: English counts up in thousands and then millions, while Chinese counts up in 千 and then 万 and then 亿, so the big units land every four zeros instead of every three. Recognizing 三万五 as 35,000 fast enough to keep listening is a separate skill from knowing what it means.
countfu trains that skill directly. Tap play, hear a short clip in clear Standard Mandarin, and type what you heard on a numeric keypad. You get instant digit-by-digit feedback and a transcript showing every number in both hanzi and pinyin. Wrong answers are saved automatically, so you can come back and retry the exact items you missed until they stick. Eight test types cover plain numbers from 十 to 亿, money in 块 and 元, dates, times and durations, rates and percentages, measurements, 11-digit mobile numbers at native speed, and conversations that hide the number inside a natural dialogue across ten real-life scenarios.
The number test is free forever. countfu Pro unlocks every advanced test type, all ten conversation topics, Mix, and Exam Mode, a timed round with limited replays where answers stay hidden until the end. There are 15,500 audio clips across multiple Mandarin voices so rounds never feel repeated, playback speed is adjustable from 0.5x to 1.5x, and the whole thing works offline with no account, no ads, and no tracking. Try it free in your browser at countfu.com. The iOS app is coming shortly.
