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.

Some 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. There's even an option that lets you type texts in order, fragment by fragment. Read a book with your fingers!
• Advanced lesson generation: auto-review slow and mistyped words after every text or generate custom lessons to practice problem words, keys, trigrams, etc.
• Graphs!
• [Your suggestions here!]

Linux users: just check out the sources
OS X users: halter73 has provided me with an (Intel) OS X build,
            if there are any problems please report it in the issue list.
            (If anyone can help providing updated builds using py2app,
            please let me know.)

For an online webapp alternative, check out the excellent Key Hero. I plan to steal some of its nicer features. :) (However, the future focus of Amphetype will be advanced analysis and better lesson generation.)
