TAUVIO
Time, measured beautifully.
A stopwatch, an online timer, a countdown timer, an hours calculator and a timesheet. All free, all in your browser.
Every Tauvio tool
Time

- Online Alarm ClockSet a time, give it a label, and the page sounds when it arrives. It rings while the tab is open.
- Pomodoro TimerTwenty-five minutes of focus, a five-minute break, a longer break after every fourth round. Every interval is yours to change.

- Kitchen TimerSeveral named timers at once, each with its own sound, with one-click presets for eggs, tea, pasta and rice.

- Interval TimerWork and rest periods over as many rounds as you set, with tabata presets and a sound at every change.

Days until
Each of these is a page of its own, counting the days to the next one in your own time zone, with the date named rather than guessed. They are listed in the order this language searches for them.
Publish a countdown of your own
A countdown page gets a permanent link and an embed snippet, with no account and no email address. Sharing and embedding are free; Tauvio Pass removes the "Made with Tauvio" mark and adds your own accent color and logo.
Stopwatch · Timer · Countdown · Hours · Timesheets
It runs on your device
Every calculation happens in your browser. Your times, rates and rows are kept in local storage on the machine you used, not on a server.
It stays accurate in the background
Timing reads the system clock instead of counting ticks, so switching tabs or locking your phone does not make the reading drift.
It works in your language
Every tool and every page is written natively rather than machine-translated, with local date, number and currency formatting.
Questions and answers
Is Tauvio free?
Every tool is free to use with no account or usage limit, including CSV export, the employee roster and JSON backup. Tauvio Pass adds the finished timesheet PDF, saved history and your branding on published countdown pages; it also removes the Tauvio credit from eligible exports.
Do I need to create an account?
No. Nothing on the site requires a sign-up. An account only exists if you buy Tauvio Pass or Tauvio Teams, so your purchase can be restored on another device.
Does Tauvio work offline?
The tools run client-side, so once a page has loaded it keeps working without a connection. Saving a purchase or loading a new page still needs the network.
Where is my data stored?
In your browser's local storage, on the device you used. Clearing site data removes it, and it is not synced between devices unless you export it yourself.
Which tool should I use to work out hours worked?
Use the hours calculator for one person's week of clock-in and clock-out times. Use the timesheet when you need several named weeks or several people in one document.
