R3CK0N
Zen mode is a free numpad typing test in your browser, with no signup: type random five-digit numbers as fast as you can and get your speed in keys per second, with accuracy and consistency.
There is no arithmetic. Every other R3CK0N drill asks your brain to produce a number and your fingers to type it; Zen isolates the second half, so you can find out how much of your mental-math time is really typing time, and train it on its own. It is also a plain 10-key speed test for data entry, bookkeeping, or anyone who lives on the number pad.
Choose a length. Timed, 15, 30, 60 or 120 seconds; or a fixed count of 10, 25, 50 or 100 strings.
Type. A five-digit string sits under the caret with the next one queued beside it. Type it digit by digit and the next string slides into place with no pause between them. Every keystroke is recorded with its timing, including the wrong ones. If your first keys arrive with NumLock off, the test says so instead of silently scoring misses.
Read your score. kps is keystrokes per second, every key you pressed; net kps counts only the correct ones. You also get strings per minute, accuracy as the share of keystrokes that were right, and consistency: how even your pace was from one string to the next, where 100% means every string took the same time.
See where you are slow. Zen's stats keep every run and plot kps over time, and on a physical keyboard they build a keypad heatmap: each digit coloured from fastest to slowest to reach, with a list of your slowest transitions between two keys. That is the part a plain typing test never tells you.
A 30-second run: 42 strings, which is 210 keystrokes, 204 of them right. Speed is 210 divided by 30, so 7.0 kps; net speed is 204 divided by 30, 6.8 kps; that is 84 strings per minute, with accuracy of 204 out of 210, 97.1%. If most strings took about 0.7 seconds but the ones with a 7 followed by a 1 took over a second, consistency comes in under 100% and the heatmap shows the 7 running hot. Now you know which reach to practise.
It is free, with no ads, and works without an account. Your runs are saved in your browser; sign in only if you want them synced across devices.
Typing tests count a word as five keystrokes, so multiply kps by 12 to get an equivalent wpm. The 7.0 kps in the example above is about 84 wpm on digits alone.
Yes. The number row and an on-screen keyboard both work, and the score is the same measure. The keypad heatmap needs a physical keyboard, because touch keyboards do not report individual key timings.
The spread of your string-to-string pace. It is 100% when every string takes the same time and falls as some strings take much longer than others, which usually points at one or two awkward key reaches.
