Why a timer makes studying easier
A visible finish line changes how hard it is to start. Knowing that a block ends in fifty minutes turns "study history" into a task with edges, and a task with edges is one you can actually begin. The break matters just as much: recall improves when study is broken into spaced blocks rather than one long sitting, so the ten minutes off is part of the method, not a reward for surviving it.
How to use this study timer
Opening this page loads a 50-minute study block and a 10-minute break, set to repeat three times — press start and it runs the whole session for you. The more useful trick is one timer per subject. Use "Add timer" to build "English 30 — Maths 50 — Break 10 — Chemistry 40", give each block a name and a colour, and the timer becomes your plan for the evening instead of a single countdown. Whatever you build is stored in the URL, so you can bookmark tonight's plan and reopen it tomorrow in one tap.
50 + 10, or 25 + 5?
Fifty minutes suits reading, essays, problem sets and anything where stopping breaks your thread — it mirrors a school lesson, which is a rhythm most people are already trained on. Twenty-five minutes suits shorter, repetitive work like vocabulary, flashcards or revision drills, and it is easier to face when you are tired or avoiding the subject. Neither number is a rule. Start with the one that matches the work in front of you, and change the length the moment it starts fighting you. If you want the shorter cycle, the Pomodoro timer is preset for it.
Making the sessions stick
Decide what the block is for before you start it — "read chapter 4", not "do biology" — because a vague block quietly becomes a block of browsing. Keep the phone out of reach rather than face down; the cost of retrieving it is what protects the session. Spend the break away from a screen if you can, since the point is to let attention recover, not to move it somewhere else. And when a block falls apart, let it end and start a clean one instead of trying to rescue it.
FAQ
Can I set a different length for each subject? Yes — every timer in the list has its own duration, name and colour, so a session can be as uneven as your workload is.
Does it keep running if I switch tabs? The countdown keeps time in the background and the tab title shows the remaining time, so you can check it without switching back.
Will my screen turn off mid-session? While a timer is running the page asks the device to keep the screen awake, so it stays visible on a phone propped up on the desk.
Do I need an account? No. Nothing is stored on a server — your setup lives in the URL, which is also how you share it.
