Contraction Timer FAQ
Is this a free online contraction timer?
Yes. It records contraction starts, stops, duration, and spacing right in your browser while the page is open.
Should spacing be measured start-to-start?
Most contraction timing uses the start of one contraction to the start of the next. This page labels that as spacing.
Can I use it for Braxton Hicks contractions?
Yes. Use practice mode if you are simply observing occasional tightening. Contact your care team if you are unsure what you are feeling.
What should I do with the contraction log?
You can copy the summary, take a screenshot, or read the recent duration and spacing aloud when speaking with your care team.
