What is OnlineCounter.site?
An online counter is a free browser tool that adds or subtracts a number each time you press a button or key. OnlineCounter.site provides that tool, plus six related counters: a tally counter for people, attendance, inventory, repetitions and events; a click counter for mouse clicks and touchscreen taps; a number counter for increasing or decreasing a numerical total; a digital counter with a large on-screen count; a button counter with a large plus button; and an online counting machine for a running count in the browser. Choose the right counter on the free online counter tools page, or start with the online counter on the homepage.
How does it work?
Open the page and press + once for each thing you count. Press − or Undo if you marked one too many. Set a starting number when you already have a partial count, and use Reset when a new count begins. Count by 1, 5, 10, 25, 100, or a custom step. On a keyboard, Space or Arrow Up adds, Arrow Down subtracts, R resets, and Ctrl or Cmd + Z undoes.
Who uses it?
- Teachers and organisers counting attendance at a class, meeting, or shift.
- Door staff and event staff counting people entering a room, shop, or doorway.
- Coaches and gym users counting exercise repetitions, laps, or intervals.

What does it not do?
A tally counter on this site does not scan barcodes, count coins, or store records on a server. A click counter does not monitor clicks on other websites. An online counting machine does not count money or parts on a production line. A digital counter on this site is a webpage, not a physical digital counter.
