Frequently Asked Questions
Why are TED Talks strictly limited to 18 minutes?
TED curators chose 18 minutes because it is long enough to flesh out a profound idea, yet short enough to hold audience attention and prevent cognitive overload.
Can I keep the timer on top of my rehearsal slides?
Yes. Press "P" to launch a Picture-in-Picture window that floats on top of your slide deck or presentation notes.
Will the timer keep working if my laptop is unplugged or on battery?
Yes. FreeTimerTools is engineered for high battery efficiency with zero heavy animations or CPU draining loops.
