Weak key drills
Your heatmap shows which keys you get wrong. This turns that into practice material dense in exactly those characters, so you drill the thing that is actually costing you time.
Frequently asked questions
- How are my weak keys chosen?
- From the per-character error data recorded during your tests, ranked by total errors rather than error rate. A key you press constantly and miss occasionally costs more time than a rare key you often fumble. Keys with fewer than eight presses are ignored, because below that a single mistake looks like a serious weakness.
- Why does the drill mix in ordinary words?
- A solid wall of symbols stops being typing practice and becomes a puzzle. Connective words restore the rhythm the drill is meant to train, while keeping the density of your target characters far above normal text.
- How many keys should I drill at once?
- Two or three. Spreading practice across eight keys means too few repetitions of each for any of them to consolidate. Fix the worst, then re-check the heatmap and move to the next.
- Where is my typing data stored?
- In your browser. Error counts never leave your device unless you choose to submit a score to the leaderboard, so drills are generated locally from your own history.
