Typistic records every key press and release while you type, then works out which finger motions slow you down or trip you up, and builds practice drills out of words that exercise exactly those motions.
Timing between every pair of keys, how long each key is held, and how much your key presses overlap. See your slowest letter pairs replayed on a keyboard, finger by finger.
A per-typist model scores motions like same-finger jumps, ring-finger reaches and outward rolls, then fills a 30-second test with words that train the ones costing you most.

Analysis is based on physical key positions, so it works the same on QWERTY, Dvorak, Colemak or your own layout.
