Typing accuracy practice: improve the keys you miss most

Why raw mistake counts can be misleading

Suppose you mistype «e» eight times and «z» four times. You might assume that «e» is the bigger problem. However, if you typed «e» 400 times, its error rate is only 2%. If you typed «z» 20 times, its error rate is 20%. Practicing «z» first may help more. A useful comparison therefore considers how many times each key was attempted.

This number describes recorded test keystrokes, not your physical keyboard or your health. Mobile keyboards, autocorrect, alternate keyboard layouts and input methods can affect the measurements.

Three practical steps

1. Finish a test: try a one-minute words test. The timer starts with the first typed character.
2. Inspect per-key error rates: scroll down to the Accuracy Lab below the keyboard heatmap. Percentages appear once a character has at least eight measured attempts.
3. Train one letter: select Train for a difficult key. Typlora prepares a 60-second passage containing that character more frequently.

You can start directly with E practice, R practice or Z practice. The text is generated in your browser.

How error rates are calculated

When you input a character, Typlora compares it with the expected character at that position. One attempt is recorded for the expected key, plus one error if the input is incorrect. Backspace does not erase the original mistake from the counter. The key error rate equals mistakes / attempts × 100.

Version 8 starts recording attempts per key. Older backups contain mistake totals but not how often a character was attempted. They remain in the historical records and heatmap, but are excluded from Typlora percentage calculations so the site does not invent a denominator.

A repeatable practice routine

Start with a one-minute typing test and focus on accuracy instead of a personal record. Pick one weak letter, then complete two one-minute drills focused on it. Finish with the same test type you started with. Compare results only when the time and conditions match: fifteen seconds of typing should not be treated as equivalent to five minutes of practice.

Short, regular sessions are usually more sustainable than occasional marathon sessions. If your hands hurt or feel strained, stop and take a break. Your typing score is not worth physical discomfort.

Local privacy and backups

Typing results and per-key statistics are stored locally in your browser. No account is needed to practice. You can export your progress to JSON, restore it on another computer, or clear your local history. Optional online tournament participation is a separate feature, with its own consent, and does not upload your typed text.

Clearing site data may erase local progress if you haven't exported a backup. Use the Progress section to keep a copy when you need one.
