Give the next block your full attention.
Run a Pomodoro-style focus session, take a short or long break, and keep a simple log of the minutes you actually spent working today.
Focus in blocks, rest on purpose
No account, no sync, no tracking — the numbers stay in this browser.
TimeBox is a Pomodoro-style timer for the way attention actually works: one block of deliberate work, a short rest, then a longer rest after every few blocks. The dial, the ring, the session log and the daily numbers all live on this page.
What the Pomodoro Technique asks for
Francesco Cirillo's method is almost stubbornly simple: pick one task, work on it for 25 minutes without switching, then rest for five. After four of those blocks, take a long break of 15 to 30 minutes. The point is not the exact numbers — it is that the block has an end, so starting is cheap and interruptions get parked instead of followed.
TimeBox keeps every length editable (1–180 minutes of focus, 1–60 for a short break, 1–90 for a long one) and lets you choose how many focus blocks come before the long break. The three presets — 25/5/15, 50/10/20 and 90/20/30 — cover the classic rhythm, an extended one for deep work, and an ultradian one for long single-task stretches.
How a session runs
- Name the task under Current task. The label travels into the session log and shows on the dial while the timer runs.
- Start the block. The needle and the outer ring both show how much of it is gone, and the browser tab title carries the remaining time so a background tab still tells you where you are.
- At the end TimeBox sounds a cue (if the sound cue is on), shows a notification (if you allowed one) and moves you on — to a short break, or to a long break once you have finished the set number of focus blocks.
- Skip ends the current block early. Skipping stays honest: a skipped focus block is not counted as focus time.
What gets counted
Only a completed focus block counts. A finished block adds its full length to today's focus minutes, increments the session count and appears in the session log with its task label and time. A finished focus block on a new day moves the day streak up by one; miss a day and the streak returns to zero. Breaks are never counted as work, and the “This week” chart reads the last seven days out of the same log — which you can export as CSV.
Honest limits, and the keyboard
Durations, stats, log, theme and notification preference are stored in this browser's local storage under a per-site key, so they survive a reload and nothing is transmitted anywhere. Notifications need the tab to be open and permission granted in the browser. The whole timer is keyboard-drivable:
- Space start or pause the block
- R or Esc reset the block
- S skip to the next phase
- ← → switch between Focus, Short break and Long break
Frequently asked questions
What is TimeBox?
TimeBox is a Pomodoro-style focus timer that runs entirely in your browser. You set focus and break durations, label each session with a task, and track daily focus minutes, streaks, and a session log — no account, no data leaves your device.
Does TimeBox save my progress?
Yes. Sessions, streaks, durations and your current task are stored in your browser's local storage, so the timer remembers your history between visits on the same device.
Can TimeBox send notifications when a session ends?
Yes — enable Notifications in the toolbar and the timer will alert you when a focus or break session completes, alongside an optional sound cue.
Is TimeBox free to use?
TimeBox is completely free, private, and open to use by anyone. It is one of the Bravest New World tools hosted on apprun.icu by Yunus Emre Vurgun.
What is the Pomodoro Technique?
The Pomodoro Technique is a time-management method from the late 1980s: work in one short, undistracted block — classically 25 minutes — then take a 5-minute break, and after four blocks take a longer break of 15 to 30 minutes. TimeBox implements exactly that cycle, and every length, including the number of blocks before the long break, stays editable.
How are focus minutes and the day streak counted?
Only a completed focus block is counted. It adds its full length to today's focus minutes, increments the session count, appears in the session log and moves the day streak forward. Breaks are never counted, and a block you skip or abandon adds nothing.
Does the timer keep running if I switch tabs?
TimeBox recalculates the remaining time from the clock rather than counting ticks, so a block finishes on schedule even while the tab sits in the background; the completion toast, sound cue and notification then fire when the page next updates. Closing the page does end the block, and an unfinished block is not logged.
