How to use it
- Tap + to count up and − to count down (or use the keyboard).
- Rename the counter by clicking its name.
- Add more counters for different categories.
- Download the totals as a CSV file when you're done.
Counting
The big + button adds one (or your chosen step), and − subtracts. On a phone, the buttons are large enough to tap without looking. On a computer, use the keyboard:
| Key | Action |
|---|---|
| Space, Enter, + or ↑ | Count up |
| − or ↓ | Count down |
Keyboard shortcuts don't fire while you're typing in a text field, so renaming a counter won't change its count.
Options:
- Step: count by 1, 2, 5, 10 or any number up to 1,000.
- Don't go below zero: on by default, so an accidental extra tap on − can't produce negative counts.
- Click sound: a short high beep counting up and a lower one counting down.
- Vibrate: a short buzz on phones that support it, so you can count by feel.
Multiple counters
Click + New counter to add up to 20 counters, for example Adults, Children and Seniors at an event entrance, or Cars, Trucks and Bikes in a traffic count. Click a counter's name in the list to make it the active one for the big buttons, or use the small + and − next to each counter directly. The heading shows the total of all counters.
Undo steps back through your last changes, including a reset. Reset sets the active counter to zero, and Reset all clears every counter; both ask for confirmation first. Download (CSV) saves the names, the counts and the total for a spreadsheet.
Your counts are saved
Counters are stored in your browser's local storage on this device. Close the tab, reload the page or restart the browser, and your counts are still there. Nothing is sent to a server, and no account is needed.
That also means counts don't sync between devices, and clearing your browser data removes them. In private or incognito windows the browser may block storage; the tool warns you if so, and counting still works until you close the window. Download a CSV if you need a permanent record.
Tips for accurate counts
- Name counters before you start, so the CSV makes sense later.
- Use a step when counting groups: a step of 2 for pairs, or 10 for boxes of ten.
- Keep the phone awake during long counts; some phones dim and lock the screen, which interrupts tapping. Your count is saved, so you just continue after unlocking.
- Turn on vibration if you count while watching something else, such as people walking through a door.
- Check the total of several counters against a single overall counter if accuracy really matters, like for fire-code capacity limits.
What people count
- Events and venues: attendance, people entering and leaving, capacity limits.
- Retail and research: customers, foot traffic, survey tallies, bird or wildlife counts.
- Sports and fitness: laps, reps, rounds, points in casual games.
- Classrooms: votes, participation, behavior charts.
- Crafts: knitting and crochet rows or stitches.
- Habits: glasses of water, cigarettes avoided, prayers or mantras.
For a timed count, pair it with a stopwatch or timer. To count words or characters in a text instead, use the word counter.
