The short version: Tally Tapper has two tools for everyday counting and planning. The tally counter keeps counts on this device. The day counter works with calendar dates and puts your choices in the page address.
Who runs it
Tally Tapper is built and maintained by DEV2REV, a small software company in Porto, Portugal. It is an independent site.
Why it exists
Sometimes you need to keep a running count. Sometimes you need to work out how many days separate two dates. Tally Tapper puts those jobs in two simple tools.
The tally counter lets you name counters, change the step and set a target. The day counter counts between dates or shows a live countdown to an event.
How the tools count
The tally counter changes a count by your chosen step. It saves your counts, counter names, step, target, and sound and vibration choices in this browser’s localStorage on this device only. These values are never sent to us. Clearing site data deletes them.
The day counter counts calendar dates. The end date is not counted by default. Business days are Monday to Friday, with no adjustment for public holidays.
The live countdown uses your time zone. The hours figure for a day total is days × 24. It is not a measurement of elapsed hours across daylight saving changes.
Dates, the event name and options are written into the page address as you change them. They appear in browser history and in any link you share. They also appear in hosting logs when that link is opened.
What to check
Check the selected dates and whether the end date is included. Business day totals do not account for public holidays or work schedules outside Monday to Friday.
Check important dates and deadlines for contracts, legal matters, medical care and travel against an authoritative source. Keep another record of important tally counts. Counts saved in the browser can be lost if site data is cleared.
How the site is paid for
The site is free and is paid for only by Google AdSense ads. Advertisers have no say over the tools or their results. Details about advertising and data are in the privacy policy.
