Gou Ninja

A website on which you can practice listening to numbers. You will have to listen to a random number plus counter said by a robot voice and type in what you've just heard. You can select a maximum amount for numbers, like 10, 100, 1000, 10 thousand and 1 million, which counters/units you want to include, and how many times one number should be repeated.
