Count-up stopwatch for duration and latency recording
Duration and latency data are only as good as the moment you hit start. This stopwatch is deliberately plain: no menus, no laps you did not ask for, just a large start-stop control and a time you can trust.
The free tier covers the core timing and tally tools; the rest of the toolkit is included with a paid plan.
What it does
- One large start and stop control that works one-handed
- Split timings for successive duration or latency measures
- Resets cleanly between trials without losing the last value
- Timings land in your session history for later charting
How it works
- 1Start the stopwatch the moment the behavior begins or the prompt is delivered.
- 2Stop it when the behavior ends to capture duration or latency.
- 3Record the elapsed time against the session, then reset for the next trial.
Questions behavior analysts ask
What is the difference between duration and latency recording?
Duration measures how long a behavior lasts. Latency measures the time between a prompt and the start of a response. The same count-up stopwatch covers both.
Can I keep several timings from one session?
Yes. Each start-stop pair can be captured as its own measure, so successive trials stay separate.
Does it work offline?
The stopwatch runs entirely in your browser, so it keeps working without a signal.
Tools that work with it
Run count-up timer without adding another app to your session bag
Every tool here shares the same learner records, session history, and export, so data collected in count-up timer is available everywhere else in your account.
