25 minutes by default, break 5, both adjustable in five-minute steps. When time is up it does not cut you off — it asks how long you really focused, and counts that.
Start the timer →No account. Nothing leaves your browser.
| It is | It is not |
|---|---|
| A focus timer with a running record of the minutes you stayed | A task manager — no projects, no subtasks, no estimates |
| Adjustable on both sides: focus 10–60 min, break 5–30 min | A website blocker — a web page cannot block other apps, and we will not pretend it can |
| Honest about overruns: 30 minutes is logged as 30 | A streak machine — there is no chain to break and no score to protect |
Not because 25 is a magic number. Because it is short enough that you stop negotiating with yourself about starting, and long enough to get past the first few minutes of friction.
The break is not a reward — it is part of the method. Attention rarely survives two rounds back to back without one. Four rounds, then a longer break: that is one set.
| Setting | Default | Why |
|---|---|---|
| Focus length | 25 min | Long enough to get in, short enough to start |
| Break length | 5 min | Leave the screen; do not drift into the phone |
| Long break | 15 min, after 4 completed | Recovery, not a reward |
| When time is up | Ring, then one more lap | The clock is still there for the minutes you actually did |
| Reminder | One short tone | Three options: tone, system notification, silent |
| Ambient sound | Off | Brown noise can be switched on, with a volume slider |
When 25 minutes are up it rings — that is the interruption, and 25 minutes means 25 minutes. But it does not throw your work away if you were mid-sentence. The dial turns red and keeps counting for one more lap, up to 50 minutes. Past that it stops counting, so a timer left running all afternoon cannot invent six hours of focus.
If you stop at 18 minutes, the 18 minutes are kept. They just do not count as a completed round. Not completing and wasting the time are different things.
This is a website. You will go watch a lecture, look something up, answer a message. The timer runs on a timestamp, so it keeps its own time and reconciles when you return. Nothing is lost and nothing is scolding you.
If you are about to study or work, open it. That is the entire instruction. Twenty-five minutes, one thing, then stop. Most people find the first ten minutes are the hard part — the timer is not what makes you focus, it just gets you past that edge. After it, flow has somewhere to start.
What it cannot do: it cannot prove you are a disciplined person. It cannot show that you are someone who focuses for hours every day. It is not evidence of anything about you. It is an accessory — a small clock next to the work — and that is all.
Other tools are built to make you feel like you are growing: streaks, badges, weekly reports with arrows pointing up, a tree that dies if you leave. We do not do that. Growth is something only you can feel. Nobody else can feel it for you, and no chart can feel it for you either.
Fooling other people is easy. Fooling yourself is easier. The hard thing is looking at yourself as you actually are, and admitting that the person you are looking at is not finished yet.
Is it free?
Yes — no account, no trial, no ads. Everything stays in your browser.
Does it work with the tab closed?
The timer keeps its own time from a start timestamp. If the page is closed while a round is running, the next time you open it, it reconciles — and if the round finished while you were away, it tells you and logs it once.
Can I change the lengths?
Focus 10 to 60 minutes and breaks 5 to 30, both in five-minute steps. Your choice is remembered.
Why is there no streak?
Because a streak turns a missed day into a loss, and then people protect the number instead of doing the work. Consistency is not the thing being trained here — attention is.
Is there a sound?
One short tone by default. You can switch to a system notification (which fires from another tab too) or go silent. Brown noise is available with its own volume slider, generated in the browser — no audio files are downloaded.
默认专注 25 分钟、休息 5 分钟，两边都能按 5 分钟一档调。到点它不切你——它先问你到底专注了多久，然后按你说的记。
开始计时 →不用注册，什么都不离开你的浏览器。
| 它是 | 它不是 |
|---|---|
| 一个会留下记录的专注计时器，记的是你坐住的时间 | 不是任务管理——没有项目、子任务、预估番茄数 |
| 两边都能调：专注 10–60 分钟，休息 5–30 分钟 | 不是网站屏蔽器——一个网页没有权限屏蔽别的软件，我们不会假装能 |
| 对超时老实：做 30 分钟就记 30 分钟 | 不是打卡机——没有连续天数，也没有分数要保 |
不是 25 这个数字有多神。是因为它短到让你不再跟自己讨价还价才肯开始，又长到够你熬过刚开始那几分钟的别扭。
休息不是奖励，是方法的一部分。人的注意力撑不过两段连着不动；四段之后给一次长休，那叫一组。
| 设置 | 默认 | 为什么 |
|---|---|---|
| 专注时长 | 25 分钟 | 长到能进去，短到能开始 |
| 休息时长 | 5 分钟 | 离开屏幕，别顺手滑手机 |
| 长休 | 15 分钟，完成四段之后 | 是恢复，不是奖励 |
| 到点怎么办 | 响铃，再给一格钟面 | 钟面还在，是为了你多出来的那几分钟 |
| 提醒 | 响一声 | 三种可选：响铃 / 系统通知 / 静音 |
| 背景声 | 关 | 可开棕噪，带音量滑条 |
25 分钟到了它就响——响就是打断，25 分钟就是 25 分钟。但它不会因为你正写到一半就把这段作废：钟面转成红色，再走一圈，最多记到 50 分钟。超过这一圈就不计了——所以一个开一下午没关的计时器，不会凭空变成六小时专注。
坐到 18 分钟停下，18 分钟照样记着。只是不算「完成一段」。没完成和浪费时间，是两回事。
这是网站。你会去看网课、查个东西、回条消息。计时按开始时间戳走，回来自己对账，什么都不会丢，也没有人指责你。
你要学习了、要工作了，就把它打开。整句建议就这一句：二十五分钟，只做一件事，然后停。多数人的困难在前十分钟——计时器本身不产生专注，它只是把你推过那道坎。过了那道坎，心流才有地方开始。
它做不到的事：它证明不了你是个自律的人，也展示不了「我每天都专注很久」。它不构成关于你的任何证据。它是个配件——工作旁边的一只小钟，就这样。
别的工具是被设计来让你觉得自己在成长的：连续天数、徽章、箭头上扬的周报、你一离开就枯死的树。我们不做这些。成长只有你自己感觉得到，别人感觉不到，一张图也感觉不到。
骗别人很容易，骗自己更容易。真正难的是敢不敢面对真实的自己，敢不敢承认此刻这个自己还不够完整。
要钱吗？
不要。不注册、不试用、没有广告，全部在浏览器里跑。
标签页关了还在计时吗？
计时靠的是开始那一刻的时间戳，不是一秒一秒往下减。关掉页面期间它按真实时间走，下次打开会对账。
时长能改吗？
专注 10 到 60 分钟，休息 5 到 30 分钟，都是 5 分钟一档。改过会记住。
为什么没有连续天数？
因为连续天数一旦存在，漏一天就变成损失，人就会开始保护那个数字，而不是做事。这里练的是注意力，不是坚持表演。
有声音吗？
默认响一声。可以换成系统通知（切到别的标签也会弹），或者干脆静音。棕噪可以开，带独立音量，是浏览器现场合成的，不下载任何音频文件。
