Auto Counter
An auto counter counts on its own on a timer instead of waiting for you to press a button. This one steps from every 0.1 seconds up to once an hour, counts up or down, uses any step size, and stops on its own when it reaches a limit you set.
The entire run is one undo, so pressing Ctrl+Z once returns the counter to where it stood before you started it.
Auto uses your step size, stops on its own at a min or max limit, and records the whole run as a single undo.

For counting that follows a clock rather than an event: pacing intervals, running a countdown, driving a display, or accumulating a figure over a set period without standing over it.
An auto counter is a counter that advances itself at a fixed time interval rather than on a button press, continuing until it is stopped or reaches a preset limit.

How to set up the auto counter
Three settings decide everything: how often it steps, which direction, and where it stops.
Set your step size
The amount added on each tick. Leave it at 1 to count one at a time, or raise it to accumulate faster without a faster interval.
Open the Auto count panel and choose a speed
Anything from every 0.1 seconds to once an hour. Fast intervals suit demos and stress tests; slow ones suit accumulating over a shift.
Pick a direction
Tick “Count down instead of up” to run a countdown. Combined with a start value and a minimum, that gives a countdown that halts exactly where you want.
Set a limit so it stops itself
Open Min / max limits and set a ceiling or a floor. The counter stops on its own when it arrives, which is what makes it safe to leave running.
Press Start auto
The count runs until it hits the limit or you stop it. Press Undo once afterwards to reverse the entire run.
What an automatic counter is actually used for
Auto counting fits anything that happens on a rhythm rather than on your input, and anything you should not have to sit and watch.
Interval training and pacing
Set a tick per work interval and let it call the rounds, rather than watching a clock while you train.
Countdowns to a number
Start high, count down, and stop at zero. Useful for stock depletion, remaining places, or a countdown on a display.
Driving a display or demo
A number that visibly climbs without anyone touching it, for a stall, a stream overlay, a shop window or a classroom demonstration.
Accumulating over a shift
A slow interval totals a figure over hours. Set it running at the start of a period and read it at the end.
Testing and development
A predictable changing number for testing a display, an animation, a screen reader or a recording setup.
Pacing a repetitive task
A tick every few seconds sets a rhythm for packing, sorting or inspection work without a metronome.
Teaching skip counting
A step size of 2, 5 or 10 with a slow interval shows the pattern building one step at a time.
Timed rounds and turns
One tick per round in a game or a workshop, so nobody has to remember whose turn it was.
Auto counter, timer and stopwatch are three different tools
These get used interchangeably and they are not the same thing. Picking the wrong one is the usual reason a setup does not do what somebody expected.
| Tool | What advances | You control | Use it for |
|---|---|---|---|
| Auto counter | A number you define | Interval, step size, direction, stopping value | Counting to a target on a rhythm |
| Timer | Time, downward | The starting duration | Knowing when a fixed period is up |
| Stopwatch | Time, upward | Start and stop | Measuring how long something took |
The practical difference is the step size. A timer counts seconds because seconds are what it measures. An auto counter can add 1, 10 or 250 per tick, so the number on screen is whatever you are actually counting — units produced, places remaining, metres covered — rather than elapsed time you then have to convert.
If you want elapsed time, use a clock. If you want a number that climbs or falls on a schedule and stops somewhere meaningful, that is an auto counter.
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.
| Feature | This online counter | Handheld clicker | Counter phone app | Pen and paper | Spreadsheet |
|---|---|---|---|---|---|
| Cost | Free | $5–$15 | Free with ads, or paid | Cost of paper | Subscription |
| Anything to install | No | Buy the device | App store download | No | Yes, or a web login |
| Several counts at once | Unlimited | One per device | Usually limited | Yes, messy | Yes |
| Fix a miscount | Undo and redo | Start over | Sometimes | Cross it out | Edit the cell |
| Counts by more than one | Any step size | One at a time | Sometimes | Manual maths | Yes |
| Below zero | Yes | No | Rarely | Yes | Yes |
| Keeps the count if you close it | Saves automatically | Until you reset the dial | Yes | If you keep the paper | Yes |
| Works with no signal | Yes, after first load | Yes | Yes | Yes | Often not |
| Keyboard and shortcuts | Full | None | None | None | Partial |
| Sends your data anywhere | Never | Never | Often, for accounts and ads | Never | Yes, to the cloud |

Frequently asked questions
What is an auto counter?
An auto counter is a counter that advances itself on a timer rather than waiting for a button press. You set an interval, a direction and usually a stopping point, and it counts on its own until it reaches the limit or you stop it.
How do I make a counter that counts by itself?
Open the Auto count panel, choose an interval between every 0.1 seconds and once an hour, then press Start auto. Set a step size first if each tick should add more than one, and a maximum if it should stop on its own.
Can the counter count down automatically?
Yes. Tick “Count down instead of up” in the Auto count panel before starting. Set a start value and a minimum limit and it becomes a countdown that halts at exactly the number you chose rather than running past it.
Does auto counting keep running if I switch tabs?
Yes. It works from the clock rather than a simple repeating timer, so when you come back the count reflects the time that actually passed. Very long absences are capped, so you never return to a runaway number.
Does an auto run fill up the undo history?
No. An entire auto run is recorded as a single undo entry, however many steps it took. Pressing Undo once returns the counter to the value it held before you pressed Start auto.
What is the fastest an auto counter can count?
Every 0.1 seconds, which is ten steps a second. With a step size above one you can accumulate far faster than that without the display becoming unreadable, since the interval stays the same while each step adds more.
Can I set the counter to stop at a number?
Yes, and this is what makes it safe to leave running. Open Min / max limits, tick Enable limits, and set a ceiling, a floor or both. Auto counting halts on its own the moment it reaches the limit.
Is an auto counter the same as a timer?
No. A timer measures elapsed time and reports it in hours, minutes and seconds. An auto counter advances a number you define, by a step size you choose, in either direction, and can stop at an arbitrary value. Use a timer for time and an auto counter for a count.
