Finger Heatmap Analyzer

Every keystroke you type is assigned to a specific finger, and over a long typing session those assignments aren't even. In standard touch typing, your index fingers do noticeably more work than your pinkies, both because they cover more keys and because the most frequent letters in English tend to fall under them. Seeing that imbalance visually, rather than just knowing it in the abstract, makes it much easier to understand why certain fingers feel tired or why certain keys keep tripping you up.

This tool records every keystroke during your drill, correct and incorrect, and builds two views from that data: a frequency heatmap showing which keys and fingers you use most, and an error heatmap showing which specific keys you miss most often. The error view is usually more useful for improvement, since it points directly at the keys worth deliberately slowing down for, rather than a vague sense that you're "not that accurate."

Type the drill below at a natural pace, don't try to game the results by typing unusually carefully or carelessly. When you finish, the keyboard below will light up according to your chosen view, and a per-finger breakdown will show the load distribution across both hands.
