Free Contraction Timer & Labor Tracker
Contraction Timer is a free, privacy-first web app for timing labor contractions. Tap once
when a contraction starts and again when it ends — it records each contraction's
duration and the interval between them, shows your average
duration and frequency, and watches for the 5-1-1 pattern (contractions
about 5 minutes apart, lasting about 1 minute, sustained for at least 1 hour) that many
providers use as a general guide for active labor.
It is 100% free with no ads, no accounts and no sign-up. It works offline, installs to your
phone's home screen, and keeps all of your data on your own device — nothing is uploaded to
a server. You can also log when your water breaks and share a clean report with your doctor
or midwife.
JavaScript is required to run the timer.
Read our contraction-timing FAQ to learn how to time contractions, what
the 5-1-1 rule means, and when to go to the hospital.
