Science of Timed Focus
Evidence-based techniques using structured work & rest intervals to leverage your brain's natural rhythms, maximising retention, minimising fatigue, and keeping motivation high.
Focus Knowledge Quiz
Test what you know about learning science & productivity
Turn βstudy biologyβ into blocks you can finish. Add a subject, the minutes it honestly needs, and a priority. Each row shows how many 25-minute sessions that block will take. Start opens the timer on that length. The list stays in this browser only, so a library computer will not follow you home, and nobody else can see the subjects you are avoiding.
Active recall beats another reread. Write a small prompt and a short answer, flip the card, and say the answer before you look. Again sends the card back to the start of the ladder. Got it moves it toward mastered. Keep cards for formulas, verbs, dates, and the exceptions you always swap. Review a few on a break, then stop when the break ends.
Small instruments for decisions that otherwise send you to another website: how long until the exam, how many sessions a task needs, what a weighted grade still requires, how long a reading will take, a twenty-second eye reset, and one sentence that says what this sitting is for. They share the page with the timer so the countdown is never the only serious thing here.
Exam countdown
Name the paper and set the date. Days and hours stay on this device. Delete the row when the paper is over.
Session calculator
Tell it how many minutes the work really needs, plus the focus length and the break. You get the number of sessions, the breaks between them, the total time, and the clock time you would finish if you started now.
Weighted grade
Score each piece out of 100 and give it a weight that acts like a percent of the course. If the weights you have typed are under 100, the note says what the rest of the course must average to hit your target, or that the target is already out of reach.
Reading pace
Word count divided by your real speed, not the speed you wish you had. The default of 220 words a minute is only a starting point. Add annotation time yourself, then set the timer to the honest number.
20-20-20 eye break
Every twenty minutes of close work, look about twenty feet away for twenty seconds. This button counts them so you do not cheat at twelve. Blink, then come back.
Session intention
One sentence. If you cannot name the object of the sitting, you are not ready to press play. The sentence stays in this browser.
On the longer break
- Roll the shoulders up and back, five times.
- Unclench the jaw and the tongue.
- Look out a window farther than the screen.
- Drink water before you open anything else.
- One slow breath that actually reaches the ribs.
