SigilType is a free typing trainer for adults. Learn touch typing in a short step-by-step course, then let adaptive practice focus on the keys and moves between keys that cost you time. Timed tests sit apart from practice, so you can see whether the gains carry over. Works with UK and US QWERTY, Colemak Mod-DH, Dvorak and Workman, and with split boards like the Corne and Planck. No account needed to start.
