Free Typing Rhythm Fingerprint Test — Consistency & Bigram Heatmap Online

Typing rhythm describes the timing pattern of your keystrokes — specifically the dwell time (how long each key is held) and flight time (gap between releasing one key and pressing the next). Consistent rhythm produces even, readable text and is associated with expert typists.

Flight time is the interval between releasing one key and pressing the next. Fast typists often press the next key before releasing the previous one — the test reports this as key overlap (rollover), a sign of practiced, fluent typing. Long or highly variable flight times suggest hesitation on certain key pairs.

The Rhythm Consistency Score (0–100) measures how uniform your keystroke timing is. It is calculated as 100 minus the coefficient of variation of your inter-key intervals — the gap between consecutive keystrokes — so it reacts to every hesitation, not just per-second averages.

A bigram is any pair of consecutive keys — for example 'th', 'he', 'in'. The test times every bigram you type, lists your fastest and slowest pairs, and can generate a one-click practice drill from your three slowest pairs.

Practice slow, deliberate typing at a steady pace before building speed — the built-in metronome lets you type to a fixed beat from 40 to 200 BPM. Then drill the bigrams the test flags as slow; these are usually awkward same-hand or cross-row combinations that benefit from targeted repetition.

Yes. Net WPM (correct characters divided by five, per minute) and keystroke accuracy are tracked live alongside the rhythm metrics, so you can see whether pushing for speed costs you consistency. Rhythm is the focus, but both headline numbers appear during and after every run.
