Questions people ask
Clear answers and limits
What are the default intervals?
The page starts with 25 minutes of focus, a 5-minute short break, and a 15-minute long break.
Are task names uploaded?
No. Task text and summary history are stored only in this browser when storage is available.
What happens if I close the tab?
An active in-memory timer stops. Saved tasks and completed summary entries can remain locally, but the tool is not a background service.
Can breaks start automatically?
Yes. Auto-start controls are optional and separate for breaks and focus phases.
Does the timer diagnose attention problems?
No. It provides a structured timer only and makes no medical or cognitive claim.
What this tool checks
Use a private Pomodoro timer for adjustable focus periods, short and long breaks, and optional task tracking. The default session begins with 25 minutes of focus, a 5-minute short break, and a 15-minute long break. Tasks and aggregate summaries can remain in local browser storage; no account or upload is required. Auto-start, sound, notifications, wake lock, and fullscreen depend on browser support. Closing the tab stops active in-memory timing. It is a planning aid, not medical or productivity certification.
What to choose and what you get
What to choose
- focus and break durations with optional task text
Result
- a local focus timer and downloadable session history as CSV
Supported use
- Adjustable focus, short-break, and long-break intervals.
- Optional local tasks, auto-start controls, notifications, and daily summary.
Before you start
- It is not a background service and cannot continue an active in-memory session after the tab closes.
Supported formats
- Accepted formats: keyboard, pointer, timing, browser state.
- Output formats: HTML report, CSV.
Browser support and permissions
- Modern browser with JavaScript; timing, scheduling, clipboard, and device behavior vary by browser.
- No camera, microphone, or screen permission is needed.
Choose the right settings
- Choose this route for repeating focus and break intervals with optional tasks.
- Use /stopwatch-timer for laps or a simple countdown without focus phases.
- Use /word-counter when the task is measuring text rather than scheduling work.
Worked example
A writing task uses a 25-minute focus interval and five-minute break while retaining only local task state.
Starting facts
- Durations and optional task text are entered locally.
- Browser suspension may delay notifications or visible updates.
Observed operation: Set the intervals, start the focus session and record the completed local cycle and optional task summary.
Review the result: Confirm session state after interruptions and use the history as a personal aid rather than an authoritative work record.
Boundary: The timer cannot ensure focus, deliver a guaranteed alarm, synchronize devices or preserve state after storage is cleared.
Choose another tool when
- A Pomodoro session is a planning aid and does not diagnose attention or measure productivity.
If it does not work
- Notification, sound, wake-lock, or fullscreen features may be unavailable in the current browser.
- Closing or suspending the tab can stop active timing even when saved task data remains.
- Local storage or download restrictions can prevent history or CSV export from being retained.
Things to know
- Phase timing and notifications depend on browser scheduling, visibility, permissions, and local storage.
Privacy boundary
Browser interaction and local results stay in the current browser session and are not sent to an Aftermath processing service. How local processing is verified.
What this tool verifies
Reports local focus and break phases, optional task state, and aggregate session summaries when the browser retains them.
Check before sharing
The timer demonstrates scheduled browser phases; it does not prove productivity, attention, or uninterrupted background execution.
