The real problem
You don't lose hours. You lose minutes — all day long.
Most people don't run out of time. They leak it in small, invisible pieces that never show up on a calendar. Here's what actually happens.
Without a timer
- A "quick check" turns into 40 minutes down a feed
- Tasks quietly balloon past the time you planned for them
- Constant switching means re-reading the same paragraph three times
- The day ends busy but without a single thing you can point to
With Big Timer
- Every task gets a start time and a visible finish line
- Distractions get postponed, not chased — because the clock is running
- One window, one task, until the digits hit zero
- You finish the day with sessions logged and real progress made
Features
Everything you need. Nothing you don't.
No dashboards to learn, no settings to configure, no accounts to create. Just the handful of tools that actually help you finish things.
A countdown you can read from across the room
Huge, high-contrast digits in a monospaced typeface so the numbers never jump around. Glance up mid-task and you instantly know how much time is left — no squinting, no clicking, no breaking focus.
Presets that match how you actually work
Jump between a 25-minute focus block, a 45-minute deep work sprint, or a 5-minute breather in a single click. Or set your own length — the timer adapts to the task, not the other way around.
Progress you can actually see
A live progress ring and a session counter show you exactly how much you've done today. Small, visible wins are what turn a good day into a habit.
Break reminders
Know when to step away. Recovery isn't a reward for finishing — it's part of how the work gets finished.
Zero-distraction interface
No feeds, no autoplay, no pop-ups competing for your attention. Just you and the clock, doing one job well.
Works anywhere, instantly
Any browser, any device, no download. Open the page and your countdown is already waiting.
How it works
Your first focus session takes ten seconds
That's the entire onboarding. No tutorial, no account, no learning curve.
Pick your block
Choose a preset or set your own minutes. Match the length to the task, not the other way around.
Press start and work
The countdown takes over. One task, one window, no negotiating with yourself until the clock runs out.
Finish, rest, repeat
Complete the session, log it, take a short break, then start the next block with a clear head.

★★★★★
“I used to study for four hours and remember nothing. Twenty-five minute blocks changed that completely — I now finish a full revision topic before my first break.”
★★★★★
“It's the only timer I've actually stuck with. No login, no ads, no friction — I open a tab, hit start, and my first pull request of the day gets written before standup.”
★★★★★
“The big digits are the whole point. I can see the countdown while I'm sketching on my tablet and stay in flow instead of checking my phone for the time.”
★★★★★
“We run it during stand-ups and design workshops. Meetings that used to drift past the hour now wrap up on time — and people actually thank us for it.”
★★★★★
“Two timed writing blocks before breakfast beat an entire afternoon of staring at a blank page. I've written more in the last month than in the six before it.”
★★★★★
“I bill by the hour, so seeing exactly where my time goes matters. Big Timer makes it impossible to fool myself about how long a task really took.”
FAQ
Questions, answered
Everything you might want to know before you press start. Still curious? Big Timer is free — the fastest way to get an answer is to try it.
Big Timer is a free online countdown timer built for one purpose: helping you plan focus sessions, manage your time, and actually finish what you start. It's designed to be readable from across the room and usable in a single click — no account, no download, no clutter.
A countdown creates a defined work window. That single constraint removes the endless "should I keep going?" decision, makes distractions easier to postpone, and gives you a natural finish line to measure against. Instead of working until you feel done, you work until the clock says done.
Most people do best with 25 to 45 minutes of focused work followed by a 5-minute break. Start with 25, and lengthen the block if you find yourself finishing before the timer does. The preset buttons let you switch in one click, so you can experiment without friction.
Yes. You can start timing sessions instantly at no cost, with no account required to use the timer. There's nothing to unlock and no credit card to enter.
Absolutely. Big Timer works well for revision blocks, timed practice papers, reading sessions, and scheduled breaks — anything where knowing exactly how much time is left helps you concentrate. Students are one of our largest groups of users.
No. Big Timer runs directly in your browser on desktop, tablet, and phone. There's nothing to download, nothing to update, and nothing that breaks when you switch devices.
