Everything a good counter tool needs

Built to replace scattered tally apps and cluttered click-counter sites with one fast, private tool.

  • Multiple counters

    Track several counts at once, one for reps, one for laps, one for inventory, and switch between them instantly.

  • Custom step size

    Increase or decrease by any amount, not just one, useful for scoring, batches, or money.

  • Automatic saving

    Every change saves to your browser automatically. Close the tab and your counters are still there next time.

  • Undo & redo

    Made a mistake? Reverse it instantly, or redo it, with a button or a keyboard shortcut.

  • Keyboard shortcuts

    Count fast without reaching for the mouse. Full keyboard control for every action.

  • Auto count

    Let the counter run itself: one step every quarter second up to once a minute, counting up or down, stopping on its own at your limit.

  • Hold to reset

    Reset is a press-and-hold, not a single tap, so you cannot wipe a long count by brushing the screen.

  • Min and max limits

    Cap a counter at a target number, or stop it going below a floor, and it refuses to pass the limit.

  • Dark and light mode

    Matches your system preference automatically, with a manual toggle if you want to override it.

  • Copy & share

    Copy the current value to your clipboard or share it directly with the Web Share API on supported devices.

  • Focus mode

    Expand the counter to full screen for distraction-free counting during a game, workout, or headcount.

  • Sound & vibration

    Optional audio and haptic feedback on every tap, easy to switch off in quiet settings.

  • Session stats

    See how many times you increased, decreased, and reset, plus your current clicks per minute.

  • Rename, duplicate, delete

    Organize counters exactly how you use them, with one click for each action.

  • Private by design

    No account, no tracking of your counts, no server storage. Everything stays in your browser.

How to use the online counter

Open the counter and start counting in a few seconds, with no sign-up or download.

  1. Open the counter

    The counter is ready to use at the top of this page. Nothing to install, no account to create, and no ads in the way.

  2. Tap + or − to count

    Use the on-screen buttons, the arrow keys, or the plus and minus keys. Space also counts up, so you can count one-handed.

  3. Set a custom start or step

    Type a number in “Start at” to begin somewhere other than zero, or change “Step” to count by twos, fives, tens or any amount.

  4. Add more counters if needed

    Select “+ New” to create another counter, then rename it so you know what it tracks. There is no limit on how many you keep.

  5. Reset, undo or redo anytime

    Press and hold Reset to return to your starting number, or use Undo and Redo to step back and forward through recent changes.

What people count with this online counter

Simple Online Counter started as a plain click counter and stayed that way on purpose. It is built for the dozens of small counting jobs that do not deserve an app download, a login screen or a spreadsheet.

  • Workout reps and sets

    Tap after every rep during a lifting session and never lose count mid-set. Set the step size to match a rep scheme like 5×5. Open the rep counter.

  • Laps at the pool or track

    Keep an accurate lap count while swimming, running or on a treadmill, and read the total off a big display. Open the lap counter.

  • Headcount at a door or event

    Count people in on one counter and out on another to get a live occupancy figure at a venue or gate. Open the click counter.

  • Stock takes and inventory

    Do a quick manual stock count in a warehouse, pantry or shop floor without opening a spreadsheet or losing your place.

  • Surveys and field research

    Record observations as tally marks in groups of five, the way a paper tally sheet works. Open the tally counter.

  • Votes and a show of hands

    Tally votes during a meeting, a classroom decision or a committee vote, and undo instantly if you double-count someone.

  • Scorekeeping for games

    Track scores in card games, board games and casual sports. A custom step size handles games that score in fives or tens.

  • Habit and streak tracking

    Count consecutive days for a habit you are building, like a no-spend streak, a reading streak or daily exercise.

  • Wildlife and bird counts

    Log sightings during a survey without looking away from the field. Sound and vibration feedback confirm each tap.

  • Traffic and footfall studies

    Count vehicles, cyclists or pedestrians passing a point, with a separate counter per direction.

  • Talking-stick and speaking turns

    Keep a fair count of speaking turns during a stand-up, workshop or classroom discussion.

  • Prayer and tasbeeh counting

    Use it as a simple digital tasbeeh counter for daily prayers and dhikr, with a max limit set to 33 or 100.

  • Production and piece counts

    Count finished units on a line or in a workshop, then copy the total straight into a report.

  • Knitting and crochet rows

    Track rows and pattern repeats with two counters, and undo a tap without unravelling your place.

Five things that stop a count going wrong

Most counting errors are not arithmetic. They come from the setup, and they are all avoidable.

  • Name the counter before you start

    An unnamed counter is fine until you have three of them. Name it after the thing being counted, not the purpose, so “Cars northbound” rather than “Traffic survey”.

  • Decide the trigger, then never change it

    Whatever makes you press the button, keep it identical for the whole session. Half the discrepancies between two counters watching the same thing come from one counting arrivals and the other counting departures.

  • Use undo instead of mental arithmetic

    If you double-tap, press Undo. Trying to remember “I am two over” for the rest of a session is how a small error becomes an unknown error.

  • Set the maximum when you have a target

    A limit turns the counter into something that tells you when you are done, which frees your attention for the thing you are counting.

  • Record the running total at intervals

    For anything longer than a few minutes, note the number every so often. If something goes wrong you lose one interval instead of the whole session.

Online counter vs a clicker, an app, paper and a spreadsheet

Every counting method trades something away. This is what each one actually costs you.

Frequently asked questions

Is this online counter really free?

Yes. Simple Online Counter is completely free, has no sign-up requirement, no usage limit and no ads. It runs entirely in your browser, so there is nothing to buy, subscribe to or install.

Does my count get saved if I close the tab?

Yes. Every counter, its name, its step size and its current value are saved to your browser's local storage automatically. Refreshing the page, closing the tab or restarting your device will not lose your place.

Can the count go negative?

Yes. Unlike most online counters, this one is not locked at zero, so you can drop below it. That matters for scorekeeping, tracking a deficit, or counting down from a starting number.

Is there a limit to how high I can count?

For everyday use, no. The counter handles values up to 9,007,199,254,740,991, which is the largest whole number a browser can hold exactly. No realistic tally, headcount or rep count will reach it.

Does this tool send my data anywhere?

No. Your counts are stored only in your browser's local storage, on your own device. They are never uploaded, never attached to an account, and no one else can see them, including us.

Can I change how much each click adds?

Yes. Set the step size to any whole number to count by twos, tens, hundreds or any custom amount instead of one at a time. Quick buttons for ×1, ×2, ×5 and ×10 sit under the step field.

Can I use more than one counter at the same time?

Yes, and there is no limit. Create, rename, duplicate and delete as many counters as you need, then switch between them from the counter list. Each keeps its own value, start number and step size.

Can I undo a mistake?

Yes. Use the Undo button or Ctrl+Z to reverse the last change, and Ctrl+Y or Ctrl+Shift+Z to redo it. The counter remembers your last 100 changes, so a double-tap is never a problem.

Does the counter work offline?

Yes. Once the page has loaded once, the counter keeps working with no internet connection, because all the counting happens in your browser. That makes it usable in a basement, a pool hall or on a plane.

Does it work on an iPhone or Android phone?

Yes. The counter is designed mobile-first, with large thumb-sized buttons, optional vibration feedback and a full-screen focus mode. You can also add it to your home screen so it opens like an app.

What is the difference between a counter and a tally counter?

They do the same job. “Tally counter” usually refers to the handheld metal clicker used for headcounts, while “online counter” refers to the browser version. This tool replaces the clicker and adds undo, multiple counters and custom steps.

Can I reset the counter by accident?

No. Reset is a press-and-hold, not a single tap, so a stray touch cannot wipe a long count. Delete also asks for a second tap to confirm. Undo will bring back a value even after a reset.

Can I set a target or a maximum?

Yes. Open “Min / max limits” under the counter, tick Enable limits, and set a floor, a ceiling, or both. The counter refuses to pass them and tells you when you have hit the limit.

Is there a keyboard shortcut to count?

Yes. Plus, Up arrow and Space all count up; minus and Down arrow count down. R resets, N creates a new counter, Ctrl+Z undoes and Ctrl+Y redoes. Escape leaves focus mode.

Can I use the counter on more than one device?

You can open it anywhere, but counts do not sync between devices. Each browser keeps its own counters locally. That is what allows the tool to work with no account and no server, and it means nothing you count is ever transmitted.

What happens if I clear my browser data?

Clearing site data or local storage deletes your counters, because that is the only place they exist. Copy any total you need to keep before clearing, or before switching to a new device or browser.

Does the counter work in private or incognito mode?

Yes, but only for that session. Private windows discard local storage when closed, so counts will not be there next time. For anything you need to keep, use a normal window.

Can I install it on my phone like an app?

Yes. In Chrome on Android use the browser menu and choose Install app or Add to home screen. On iPhone use Share then Add to Home Screen in Safari. It then opens full screen with no browser bar.

Why does the reset button need holding down?

Because a single tap is too easy to trigger by accident, and losing a long count to a stray touch is the worst thing a counter can do. Holding for under a second confirms you meant it.

Can the counter count by itself, without me tapping?

Yes. Open the Auto count panel, choose a speed from every 0.1 seconds to once an hour, and press Start auto. It uses your step size, counts up or down, and stops on its own when it reaches a min or max limit.

What is the auto count feature for?

Anything that happens on a fixed rhythm rather than on your input: pacing intervals in a workout, timing rounds, running a countdown, driving a display during a demonstration, or accumulating a figure over a set period without standing over it.

Does auto counting fill up my undo history?

No. An entire auto run is recorded as a single undo entry, so pressing Undo once returns the counter to the value it held before you started, however many steps it took while running.

Does auto count keep running if I switch tabs?

Yes. It works from the clock rather than a simple timer, so when you return the count reflects the time that actually passed. Very long absences are capped so you never come back to a runaway number.

How do I make the counter count down automatically?

Tick “Count down instead of up” in the Auto count panel before pressing Start auto. Combined with a custom start value and a minimum limit, that gives you a countdown that halts exactly where you want it.

What is a simple counter?

A simple counter is a tool that increases a number by one each time you press a button, so you do not have to hold a running total in your head. The term also covers handheld mechanical clickers and, in programming, a variable that increments inside a loop.

How does an online counter work?

A small script in your browser listens for a click, tap or keypress, adds your step size to the stored value, and redraws the number on screen. Nothing is sent anywhere: the total lives in your browser's local storage, which is why it keeps working offline.

What is an online counter used for?

Most commonly headcounts at a door, workout reps, pool lengths, stock takes, survey tallies, game scores, and dhikr or prayer counts. Anything where events arrive faster than you can write numbers down, or where you need several separate counts running at once.

Are online counters free to use?

Most are, including this one, with no sign-up and no download. Some charge for team syncing, cloud backup or removing ads. This counter is free with no usage limit, carries no advertising, and stores nothing on a server, so there is no paid tier to upsell.

How do I use my phone as a counter?

Open this page in your phone's browser and tap the large plus button. On a Samsung Galaxy there is also a built-in tally counter inside Edge panels, under Settings, Display, Edge panels, Tools. App-store counters work too, but a browser needs no install.

What should I look for in a free online counter?

Four things decide whether one is usable beyond a minute: undo for a miscount, several named counters at once, a custom step size, and counts that survive closing the tab. Negative numbers and a min or max limit matter for scoring and targets.
