Is WorkThoseKeys free to use?

Yes. All lessons, targeted practice and book mode are free — you only sign in with Google so your progress and stats are saved.

Which keyboard layouts and languages are supported?

WorkThoseKeys supports the Swedish (Nordic) layout and the US English layout, with a matching interface and lesson content in Swedish and English.

Net WPM is your typing speed after errors are subtracted, so accuracy counts as much as raw speed. WorkThoseKeys tracks it for every session.

Every keystroke is recorded per character, so the app knows which keys and finger movements you miss most and can generate drills that focus on them.

A level runs until you reach the character goal, 150 characters by default. You can change that in Settings.
