Study Timer
A study timer gives your revision a clear start and finish so you focus instead of drifting. This one is set to a 30-minute block by default - Adjust it to any length, start, and it counts down full-screen to a clear alarm.
Tip: press Space to start or pause, R to reset, F for full screen.
About the Study Timer
A study timer splits your work into focused blocks with short breaks, so you learn more and stall less.
A study timer turns a big, scary task into small, doable chunks. You pick a block of time, hit start, and give that one subject your full attention until the bell rings.
The magic is the finish line. When you know a break is coming soon, it's easier to sit down, stop scrolling, and actually begin. That's how a simple clock beats procrastination before it starts.
Pick a study block that fits the task
Not every study session needs the same length. Quick review works best in short bursts. Deep, tricky material needs longer, quiet stretches called deep work. Match the block to the job:
| Block length | Best for |
|---|---|
| 15 min | Flashcards, quick revision, warming up, or a subject you dread |
| 25 min | Classic Pomodoro focus - Reading, notes, practice questions |
| 45 min | Essays, problem sets, and steady homework that needs a flow |
| 90 min | Deep work on hard topics, past papers, or big projects |
New to timed study? Start with a 25-minute timer and a 5-minute break. Once that feels easy, stretch to a 50-minute block with a 10-minute rest.
Tip: Write one clear goal before you start each block - 'finish 10 practice problems,' not just 'study math.'
Tip: Put your phone in another room during the block. The break is when you check it, not the middle.
Tip: Track how many blocks you finish each day. Watching the count grow keeps you motivated.
Why timed study blocks help you remember more
Your brain isn't built to focus for hours straight. Attention fades, and re-reading the same page stops working. Short blocks with real breaks keep your mind fresh, so each minute counts for more.
Timers also power spaced study - Spreading revision across several days instead of cramming the night before. A few short, timed sessions this week beat one long panic session. That gap between reviews is what moves facts into long-term memory.
