Billable Session Timer & Pomodoro Focus Timer — Time That Turns Into Invoices
Start the clock on a client task and watch worked time turn into billable value in real time, or switch on focus mode to work in Pomodoro focus and break sprints instead. Either way, breaks never get billed, and a finished session becomes an invoice line with one click.
No sign-up. Your session log saves in this browser.
Clients you've timed before and your session log save in this browser, so a closed tab or a running timer picks up right where you left it.
We'll nudge you at 80% and 100% of this.

Focus mode (Pomodoro)
Break time is never billed: the moment a break starts, the billable clock pauses automatically, so the money figure and the session log only ever count focus time.

Reminders
Heads up: we can't mute your operating system's notification settings for you. If you use Do Not Disturb / Focus modes, check them separately: one-line tip for macOS Focus / Windows Focus Assist.
macOS: System Settings → Focus → allow this browser, or turn Focus off while timing. Windows: Settings → Focus Assist → set to Off or Priority only with your browser allowed.
A billable session timer tracks focused work time by client and task, then converts it directly into an invoice line. An optional Pomodoro focus mode structures the work itself.
Why track billable sessions instead of guessing
Most freelancers estimate hours after the fact, reconstructing a day from memory at invoice time, and that quietly rounds down real work. A session timer anchored to the clock closes that gap: every focused block of client work becomes an exact duration the moment you stop it, with the euro or dollar value already attached, so there's no separate step where "about three hours" turns into a number you have to defend.
The real value isn't the stopwatch. It's what happens the second you hit stop. A logged session already knows the client, the task, the rate, and the amount, so it becomes an invoice line without re-typing anything. That's also where scope creep gets caught early: if a session runs past the time you planned for it, that's the same signal that feeds a change order, since extra time on a fixed-scope task is exactly the moment to raise one instead of quietly absorbing the hours.
What is the Pomodoro Technique?
The Pomodoro Technique is a time-management method built around short, focused sprints, typically 25 minutes of concentrated work followed by a 5-minute break, repeated in cycles, with a longer break after several rounds. A fixed, short deadline makes it easier to resist distraction than an open-ended "work until done" block, and the scheduled breaks prevent the fatigue that creeps in during long unbroken stretches. Turn on focus mode above and pick the 25/5 preset, the longer 50/10 preset for deep-focus tasks, or set your own custom focus and break lengths. The timer runs the cycle, counts completed focus rounds, and tells you which phase you're in.
Does the timer bill my break time?
No. When focus mode is on and a break phase starts, the billable clock pauses automatically and only resumes when the next focus phase begins. That means the money figure, the decimal hours, and the session log all reflect focus time only; break minutes are tracked for the cycle but never appear in what you'd invoice a client. You don't have to remember to pause anything yourself.
Does this replace a full time-tracking app?
No, it's deliberately narrow: it times one session at a time and turns it into a billing line, without projects, teams, or reports to configure.
What happens if I close the tab while the timer is running?
The timer anchors to real clock timestamps, not a countdown that resets, and saves its running state to your browser. Reopen the page and it picks up exactly where it left off.
Will it notify me if I go over my planned time?
If you set a planned duration, you'll get an in-page nudge at 80% and again at 100%, plus an optional browser notification if you grant permission. We can't override your OS's own Do Not Disturb settings, though.
What is the Pomodoro Technique?
A time-management method of short focused work sprints (classically 25 minutes) followed by a short break, repeated in cycles. Turn on focus mode above to run 25/5, 50/10, or custom-length cycles inside this timer.
Does the timer bill my break time?
No, when focus mode is on, the billable clock pauses automatically the moment a break starts, so the money figure and session log only ever count focus time.
