Session markers
Chronological checkpoints in this session
Add a marker when you finish a chapter, practice set, break, or topic.
Study Stopwatch
Track study time without choosing a fixed countdown or Pomodoro cycle.
How to use the study stopwatch
Start when you begin studying, pause when the session stops, and resume from the same elapsed value. Add a marker without stopping the clock when you reach a useful checkpoint. The tool is quiet by default and does not play ticks, marker sounds, or completion audio.
Study stopwatch vs study timer
The Study Stopwatch counts upward for an open-ended session. The Study Timer counts down from a fixed duration. Choose the stopwatch when you do not know the session length in advance, or choose the timer when you want a planned stopping point.
Study stopwatch vs Pomodoro
A Pomodoro timer alternates repeated work and break cycles. This stopwatch keeps one continuous elapsed-time session with optional markers. Neither method is universally better; the useful choice depends on whether you want open-ended tracking or structured cycles.
Useful session markers
Add a marker after a chapter, practice set, break, or topic change. Markers are simple elapsed-time checkpoints in chronological order. They have no required text field, are not saved to a server, and disappear when you reset or reload the page.
Accuracy and limitations
This page measures practical browser-based elapsed time. Display refresh, browser scheduling, device performance, background behavior, and input delay can affect millisecond-level readings. It is intended for study tracking, not certified measurement.

Study stopwatch FAQ
Does the study stopwatch have a fixed end time?
No. It counts upward from zero until you pause or reset it. Use the Study Timer when you want a fixed-duration countdown.
What are session markers?
A marker records the current elapsed time without stopping the stopwatch. You can use markers for a completed chapter, practice set, break, or topic change.
Will it keep running in a background tab?
The browser may reduce screen updates in a background tab. When the page becomes visible again, the displayed elapsed time is reconciled from the browser's monotonic timing clock, subject to browser and device behavior.
Is study information sent to analytics?
No marker content or elapsed value is sent by this tool. Markers stay in this page's memory and are cleared by reset or reload. Consent-gated analytics may record the canonical page path only.
