Study timer — track total focused study time
Count up through study sessions to track your real focused-study time honestly. Tap Start at the beginning of a session, tap Pause when you take a break, tap Resume to restart. The total elapsed time is the visible number; lap markers segment chapters or topic transitions. This is count-up, not Pomodoro count-down — different tool for a different pattern. You're studying for an exam in three weeks and want to know honestly how many hours you've put in. Tap Start when you sit down, study, tap Pause when you're done. The displayed total is your session time. Add it to a notebook or spreadsheet at session-end. Over the three-week study window, the cumulative count tells you whether your study time is matching your study plan. Pure tool, no video distraction. Study-with-me YouTubers dominate "study timer" search results, but those want you in their stream for hours. Plinkr is a stopwatch and nothing else — no music, no chat, no "subscribe for more" overlay. For users who want background focus music, use a music app in another tab; the timer stays separately countable.

Frequently asked questions
Does this do Pomodoro 25-minute intervals?
No. Pomodoro is a count-down pattern with an alert at 25 minutes — different tool primitive. Plinkr's stopwatch counts up. For 25-minute Pomodoro intervals with a notification, use a countdown timer or a dedicated Pomodoro app. Honest count-up tracking is better when the goal is total focused-study time across a long session, not fixed-interval blocks.
Will it pause itself when I leave the desk for a break?
No. The stopwatch keeps running until you manually tap Pause — Plinkr can't detect when you're physically away from the screen. The honest workflow is to tap Pause whenever you step away, then Resume when you sit back down. The lap button is for marking topic transitions, not break tracking.
Can I leave the tab open all evening and the time still be accurate?
Yes. The stopwatch is anchored to the system clock rather than a JavaScript interval, so backgrounding the tab or putting the laptop to sleep doesn't introduce drift. Open the tab at 7pm, work through to 11pm with various tab-switches and short breaks, the displayed total reflects actual elapsed time you didn't pause through.
Is there a daily total or a streak counter?
No. Each session is independent — close the tab and the count resets. Plinkr handles the timing primitive; cross-session totals and streaks are a different tool's job (study apps, spreadsheets, journals). Many users screenshot the session-end display and paste it into a notebook to build their own log over weeks.
