Click Counter

The reason mechanical tally counters existed for a century is that counting and looking are hard to do at the same time. If you have to find a button on a screen for every item, you lose your place in whatever you are actually counting. That is why the space bar is bound here: you can watch the door, the shelf or the lane and count without your eyes leaving it. The step setting handles the case where items come in fixed groups — counting cases of twelve, or scoring in threes — which is far less error-prone than counting to twelve in your head between clicks. Running several counters at once is what makes this genuinely more useful than a physical clicker, since categorising as you count is normally the hard part of a manual tally; the percentage under each counter updates live, so the breakdown is visible while you are still counting rather than only after you stop.

Each click adds the counter’s step, which defaults to one. The running total is the sum of every counter, and each counter’s share is its own count divided by that total. Counts are clamped at zero, because a tally of things that happened cannot be negative.

Counts are stored in this browser on this device, so they do not sync anywhere and clearing browsing data resets them. Keyboard shortcuts drive the first counter only — the rest need a click. There is no timestamped history, so you can see the totals but not when each count happened, and counters will not go below zero. A maximum of eight counters can run at once.

Counting three product types at a stall — 42, 17 and 8 — gives a total of 67, with the first line making up 63% of everything sold.

1. Click the plus button, or press the space bar, to count.
2. Rename a counter by typing over its label.
3. Add more counters if you are tallying several categories.
4. Download the CSV when you have finished counting.

• Forgetting the step is set above one and over-counting the total.
• Expecting the space bar to drive whichever counter was clicked last — it always drives the first.
• Relying on the counts surviving a browser data clear.
• Resetting everything to zero before exporting the CSV.

A digital tally counter. Click, or press the space bar, and the number goes up. Run up to eight named counters side by side, set a custom step, see each one’s share of the total, and export the lot as a CSV when you are done.

Anyone counting things by hand — stock, attendance, laps, repetitions, or survey responses.

• The space bar and arrow keys count, so you never have to look at the screen.
• Up to eight named counters run at once, each with its own step size.
• Counts survive closing the tab — they are saved in this browser.
• Export to CSV to get the numbers into a spreadsheet.

• Counting stock or inventory items by hand.
• Tracking attendance or people through a door.
• Counting laps, sets or repetitions during exercise.
• Tallying survey answers or observations across several categories at once.
