Counter
Multiple named counters with history, totals and CSV export. Useful for counting anything, anywhere.
Total: 0
How to use
- Add counters with "Add counter" and give each one a meaningful name.
- Count with the +step and −step buttons. Change the step field to adjust how much each press adds or removes.
- The total of all counters is shown at the top.
- Open "History" on a counter to see when each value was recorded.
- Use "Export CSV" to download the full history of every counter as a CSV file.
Notes
- Counters are stored only in this browser on this device (localStorage). Nothing is sent to a server.
- History keeps the latest 200 changes per counter; older entries roll off. Export a CSV to keep a permanent record.
- Resets are recorded in the history too. Clearing your browser data removes your counters.
FAQ
- Can a counter go below zero?
- Yes. Keep pressing −step and the value goes negative.
- What does the CSV contain?
- Three columns — counter name, ISO timestamp and value — covering the history of every counter.
- Do counters survive closing the page?
- Yes. They are kept in localStorage, so reopening the page in the same browser picks up where you left off.
