Online Counter
A free tally counter with custom steps, undo, history, and shareable state.
The online counter at setalarmclock.net is a tally you increment or decrement with a click — set a step, tap up or down, and it keeps your running total safe across reloads.
It’s more capable than a handheld clicker: custom step sizes up to a million, an undo stack, and a history of your recent changes.
What the full online counter does
- Click to increment; shift-click or right-click to decrement; dedicated +/− buttons
- Step presets 1, 5, 10, 25, 100 plus a custom step up to 1,000,000
- Undo stack (up to 50) and a history of the last 10 changes
- Reset and copy value to clipboard; count mirrored in the tab title
- State persists in your browser and is shareable via URL
- Keyboard shortcuts for increment, decrement, undo, and step presets
The counter is the one tool here without an embeddable widget yet — so this page sends you to the full version, where the undo history, custom steps, and shareable state all live.
Because your count and step size persist in the browser and travel in the URL, you can close the tab mid-count and pick up exactly where you left off, or hand the running tally to someone else with a link.
Common use cases
- Counting attendance at an entrance
- Inventory and stock-taking
- Reps, sets, and laps
- Tallying votes or survey responses
- Keeping score in games
