About the Study Timer

Free study timer for focused homework, revision, reading, and exam prep. Start a 25 minute focus session with sound alerts and no sign-up.

TimerHub calculates remaining time from an absolute finish timestamp, so missed browser callbacks do not create drift. Read the timing accuracy methodology and reproducible tests.

How to Use the Study Timer

  • Press Start — or the Space bar — to run the 25 minute countdown. Space also pauses and resumes it; R resets it
  • Adjust by 1 minute with the +/- buttons while it runs, toggle Repeat to loop it, and check the finish time shown under the display
  • Use the Fullscreen control below the timer for a room-sized countdown (Esc to exit)
  • Choose or mute the alarm in the header's sound settings, and pick a background sound — rain, ocean, fireplace or brown noise — that fades out at zero
  • Enable notifications to be alerted when your study timer finishes in a background tab, and add ?autostart=1 to the link to start the countdown on load

Frequently Asked Questions

Is 25 minutes a good study timer length?

Yes. Twenty-five minutes is long enough to make progress and short enough to stay focused. If you need more time, try 30, 45, or 60 minute sessions.

Should I take breaks between study timers?

A 5 minute break after a 25 minute study timer is a good default. For longer sessions, take a longer break every few rounds.

Can I use this for homework on mobile?

Yes. The study timer works in mobile browsers, so you can keep it open beside notes, books, or a laptop.
