Numberace helps assess individual's primary ability to work with numbers. This is one of seven primary mental abilities, the others being word fluency, verbal comprehension, spatial visualization, associative memory, reasoning, and perceptual speed. As it is primary, it can be present even in individuals with no math education or practice in number crunching.

Those performing good on Numberace tests may be less prone to errors in working with numbers; they may be naturally predisposed to number crunching, and have a higher stamina in these types of jobs.

Numberace measures time taken to complete the count and the counting speed. You can:

- Count to 10, 20, 50 or 100
- Choose classic or fancy fonts
- Choose static or animated mode
- Watch your speed on speedometers live
- Get parameters of a count (time, speed) compared to previous counts
- Keep results in your records file.
