Hi Matt — In my experience it varies from on and off within 10–20 seconds to over a minute.

My specific use case is as a stopwatch for a line/queue, where the button would get pressed once to start and then again once the person reaches the front of the queue (which would generally be longer than 5 minutes). I’ve been looking for something that will record the information remotely (so that it can’t be tampered with on the device; otherwise I’d use an actual stopwatch) and record the information without intervention (except for having to push the button).

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
