Practice

The pool the engine pulls from in time, words, and adaptive modes. English lists run 1k → 50k by frequency. Code lists draw from real syntax. Punctuation and Numbers are focused drills. Browse the full lists →
Only changes the visual layout of the heatmap on the stats page. The engine reads KeyboardEvent.key directly from your OS, so typing already uses your real layout — no need to tell it.
Font used in the typing surface only. Other surfaces stay in Inter / Lora.
Visual style of the cursor in the typing surface.
Allow forward typing past errorsWhen on, you can keep typing after a mistake (the wrong char is marked red and you move on). When off, the cursor refuses to advance until you fix it.
Show live wpm during testUpdates the WPM number in the toolbar in real time. Turn off if you find the changing number distracting.
Smooth caret motionAnimates the caret between characters. Off = instant jumps for lower latency.

Typing assists

Behavioral toggles that change how the engine reacts to errors and spacing. All persist per profile.

Stop cursor on errorCursor refuses to advance until you hit the right key.
Forgive errorsAuto-correct trivial mistypes (off-by-one near-miss, swapped adjacent letters).
Space skips wordsPressing space mid-word jumps the cursor to the start of the next word.
Ignore capitalizationTreat A and a as equivalent — useful when shift fatigue distorts your real wpm.
Skip punctuationAuto-skip . , ; : ? ! ' " in source text.

Visual aids

Show virtual keyboardSVG keyboard below the surface highlights the next-expected key in accent color.
Color-code keyboard by fingerTints each key with its finger's color, adds a legend strip, and pulses the next-expected key. Requires the virtual keyboard to be on.
Show tickerStrip below the surface pulses green/red per keystroke and shows rolling 5-second WPM.
Hide UIHide the toolbar + actions during a session for distraction-free typing.
