This tool is for informational purposes only and is not a substitute for professional medical advice, diagnosis, or treatment. The "5-1-1 rule" (contractions 5 minutes apart, lasting 1 minute, for 1 hour) is common guidance, not a rule every provider or every labor follows exactly. Voice mode listens only while it's on and this page is open, never in the background. If you think you're in labor or something feels wrong, call your provider or go to the hospital, don't rely on this timer alone.
