Built for real timing workflows
One online timer for every kind of timing
Nobuf combines a countdown timer, multiple parallel timers, a lap stopwatch, and repeatable interval sequences in one private browser workspace. Use it immediately without an account, then keep active timers accurate when the tab is throttled or refreshed.
Multiple countdown timers
Run independent timers together, schedule them to finish at the same time, stagger their starts, or execute a selected sequence.
Fullscreen timer display
Show one clear clock for a classroom, presentation, kitchen, workshop, or shared screen, with an obvious exit control.
Stopwatch with lap and split
Measure elapsed time and compare lap and split results without mixing stopwatch records into countdown history.
Tabata and interval timer
Run HIIT, boxing, breathing, warm-up, work, rest, and cool-down stages with repeatable rounds and local cues.
Accurate after refresh
Timers reconcile from target timestamps instead of trusting delayed interval ticks, then restore active state from local storage.
Private and offline-ready
Timer names, presets, laps, and history stay in this browser. Core features can work from same-origin cached assets.
Popular ways to use an online timer
The same precise engine adapts to everyday timing without forcing every workflow into a single 25-minute template.
Cooking and kitchen timers
Label several dishes, run them in parallel, and see which oven, tea, or preparation timer finishes next.
Classroom and presentations
Use the fullscreen display for quizzes, activities, speaking limits, workshops, and visible meeting breaks.
Workout and HIIT intervals
Choose Tabata, boxing, or custom work/rest rounds with warm-up, cool-down, sound, and vibration fallbacks.
Meetings, study, and work
Time agendas, reading, exams, design reviews, uploads, experiments, or any task that needs a clear deadline.
Accurate after background tabs and refreshes
Browsers can delay callbacks when a tab is hidden. This timer treats timestamps—not tick counts—as the source of truth, so the displayed result can reconcile when the page becomes active again.
- Active countdowns and stopwatches are restored from versioned local state.
- One primary tab owns completion records and sound to avoid duplicate alarms.
- Browser and operating-system limits are shown honestly; a closed browser cannot guarantee a native alarm.
Plan time beyond a single timer
Use the right Nobuf tool when the job involves focus planning, time zones, or exact timestamp conversion.
