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

  1. 1Start the stopwatch the moment the behavior begins or the prompt is delivered.
  2. 2Stop it when the behavior ends to capture duration or latency.
  3. 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.
