How to use the study timer
- Type a Subject such as Math or Biology if you want your minutes logged under it. The page reads this field when a block ends, so you can fill it in after you start.
- Set Study (min) from 1 to 240 and Break (min) from 1 to 120, or tap a quick cycle: 50 / 10, 45 / 15, 90 / 20 or 30 / 5.
- Choose whether to Start the next study block after each break, and whether Sound is on.
- Press Start. When a study block ends you hear two beeps, the minutes are added to the log and the break begins. Three lower beeps end the break. Pause freezes the clock, Skip ends the current phase early, and Stop ends the session.
Skipping or stopping during a study block still logs the minutes you completed. For the classic 25 and 5 rhythm use the Pomodoro timer, or try the focus timer for custom deep work sessions.
How the log works
Each phase stores the clock time at which it ends, so the display stays accurate even if the page is busy. The log keeps seconds per subject for today's local date, treats Math and math as one subject, and shows whole minutes. A block stopped within its first 10 seconds is ignored as an accidental start. The log is saved in this browser only and a new day starts an empty log. Clear today's log wipes it early.
Worked example with the default settings
The page opens on 50:00 with "Press Start. Next: 50 min of study, then a 10 min break." Enter Math and press Start: the clock counts down from 50:00 and the line reads "Block 1. 0 min studied today. Next: 10 min break." After 50 minutes you hear the beeps, the log shows "Math: 50 min" and "Total today: 50 min (1 block)", and a 10:00 break starts. With auto-start on, block 2 follows. If you change the subject to Physics and press Stop 20 minutes in, the log gains "Physics: 20 min" and the total becomes "1 h 10 min (2 blocks)".
Limits and edge cases
- If your computer sleeps during a block, the timer still counts that time as studied. Pause first if you step away.
- Edits to the lengths apply from the next phase, not to the one already running.
- Browsers can delay alerts in a background tab. Keep the page open; while a session runs it asks your browser to keep the screen awake where that is supported.
Study timer FAQ
What is the 50/10 study method?
You study for 50 minutes without switching tasks, then rest for 10. It is a longer cousin of the 25/5 Pomodoro cycle and suits work that takes time to warm up, such as math or programming. No study proves that 50/10 is the best split, so treat it as a starting point and adjust.
How long should I study before taking a break?
There is no fixed answer. A 2022 meta-analysis of 22 samples found that short breaks modestly raised energy and lowered fatigue, and that recovering from very demanding tasks may take breaks longer than 10 minutes. If your attention drifts before the bell, shorten the study block.
Does it log my time if I stop early?
Yes. Stopping or skipping during a study block adds the minutes you completed to that subject. Blocks shorter than 10 seconds are ignored, and time in breaks is never logged.
What should I do with the study log?
Use it to spot subjects that are getting no time. A major review of learning techniques rated spreading study over several days and testing yourself as more effective than rereading, so spread subjects across the week and use study blocks for practice questions.
