Study Timer - Pomodoro Focus Sessions

How the Study Timer Works

1. 01Pick a preset (25/5 Pomodoro or 50/10) or set custom focus and break lengths.
2. 02Press start: the countdown runs on screen and in the browser tab title, so it stays visible from other tabs.
3. 03When the focus block ends, the timer flips to a break automatically, with an optional soft beep.
4. 04Completed sessions and total focused minutes are tallied for today and stored in your browser.

Focus Blocks That Fit Your Work

The 25/5 pattern is the classic Pomodoro Technique developed by Francesco Cirillo: 25 minutes of single-task focus and a 5 minute break. The 50/10 preset suits deeper work like problem sets or writing, where 25 minutes ends just as you warm up. Attention research suggests most people sustain high-quality focus for roughly 45 to 90 minutes, so treat the presets as starting points and adjust the custom fields. The daily counter turns studying into visible progress: four 50-minute sessions is 200 focused minutes, a genuinely strong study day.

When to Use This Timer

Use it whenever starting feels harder than continuing: exam revision, thesis writing, coding assignments, or clearing an inbox. The short committed block lowers the barrier to starting, and the visible countdown creates gentle urgency that counters procrastination. It also works for timed practice exams: set a custom focus length matching the real exam duration and work under realistic pressure.

Common Use Cases

• —Run Pomodoro rounds during exam revision and track how many sessions each subject received. Flashcard Maker - Study with Spaced Repetition
• —Use 50/10 blocks for thesis writing or programming assignments that need deep concentration.
• —Set a custom block matching your exam length to do practice papers under realistic time pressure.

Tips

• ✻Decide the single task for a block before starting it; the timer enforces time, not focus.
• ✻Actually leave your desk during breaks; the recovery is what sustains the later blocks.
• ✻Check the focused-minutes counter at day's end and set a modest minimum for tomorrow, for example 100 minutes.

Frequently Asked Questions

What is the Pomodoro Technique?→

A time management method from the late 1980s by Francesco Cirillo: work on one task for 25 minutes, break for 5, and take a longer 15 to 30 minute break after four rounds. The name comes from the tomato-shaped kitchen timer he used. The structure works as a commitment device that makes distractions easier to postpone.

Should I use 25/5 or 50/10?→

Use 25/5 for tasks you resist starting or that fragment easily, like flashcard review or email. Use 50/10 for deep work such as writing, mathematics, or programming, where a 25 minute block ends mid-thought. If you consistently hit the end of a block still fully focused, lengthen it with the custom fields.

Does the timer keep running when I switch tabs?→

Yes, and the countdown is written into the browser tab title, so you can see the remaining time from any other tab. Note that closing the tab entirely stops the timer; the daily session stats survive because they are stored in localStorage.

Where are my session statistics stored?→

Only in your browser's localStorage, keyed to today's date. The counters reset automatically each day and are never sent to a server. Clearing browser data or switching devices starts the count fresh.

How does the sound work and can I turn it off?→

The beep is off by default. When enabled, a short soft tone is generated with the Web Audio API at the end of each phase, with no audio files loaded. Most browsers require you to have interacted with the page first, which pressing start satisfies.
