Counter
Big buttons, big number, zero friction. Tap to count, hold for fast repeat. Works with thumb on mobile.
What to count
People entering a room, laps you swim or run, drinks poured, boxes on a shelf, button presses in an experiment. Hold + or − for fast repeating. Step field lets you count by 2s, 5s, 10s — whatever makes sense.
Reliability
Nothing saved in browser storage. Close the tab = reset. If you are counting something important (event attendance?), take a screenshot before leaving. The counter works fully offline once loaded.
Frequently asked questions
Count backwards?
Yes — tap − or hold it down. Goes negative freely.
Maximum?
JavaScript numbers up to 2^53 − 1 (~9 quadrillion). You will not hit this.
Save my count?
Not automatically — no localStorage used. Take a screenshot if you need to record.
Work offline?
Yes — bookmark once, loads from cache. Add to home screen on mobile for one-tap access.
Undo accidental reset?
No undo. Take screenshots periodically if catastrophic.
