Amphetype

Amphetype is a layout-agnostic typing program aimed at people who don't need an on-screen keyboard, but would still like to improve their speed and accuracy.

The program features: WPM, accuracy, and viscosity (as the opposite of fluidity) statistics on texts, words, keys, and trigrams. Historical data can be grouped in several different ways (by days, averages of 10, etc.).
You can generate text fragments to type from Project Gutenberg or any other plain text source to practice typing with your favorite novel.
