What is a contraction timer?
A contraction timer is a tool used during labor to measure how long each contraction lasts and how far apart contractions are. A contraction tracker records each contraction and calculates the interval between them. Contraction timer apps automate this so you do not have to count manually during labor and delivery.

When to start using a contraction timer
Start using a contraction timer when you notice regular tightening in your abdomen or lower back. Record at least six contractions to identify a pattern. Early labor contractions may last 30 to 60 seconds. As labor progresses, contractions become longer, stronger, and closer together. An app to track contractions helps you see this pattern clearly.
What is the 5-1-1 rule for contractions?
The 5-1-1 rule means contractions come every 5 minutes, last 1 minute each, and continue for 1 hour. This pattern typically indicates active labor. Some providers use the 4-1-1 or 3-1-1 rule depending on circumstances. ContractionTimer.io detects these patterns and alerts you when contractions match.
How long do contractions last when they first start?
Early labor contractions last between 30 and 60 seconds. As labor progresses, contractions last 45 to 90 seconds and occur every 3 to 5 minutes. A contraction tracker helps you see whether contractions are getting longer and closer together.
Are contractions only 30 seconds?
Early contractions can last as little as 30 seconds. As labor advances, contraction duration increases. Contractions lasting 60 seconds or more at regular intervals generally indicate active labor.

This app is incredible, as it made my life so much easier, and I absolutely loved it! It told me accurately when to pack my bags for the hospital. I appreciated being able to delete a contraction time after I accidentally pressed the button, as this could have ruined the stats. Thankfully, I was able to take sleep during contractions thanks to the relaxation music tracks they included. I downloaded this app to help me keep track of my contractions. I showed the nurse when they started and all the contraction times I had up until we got to the hospital. Thank you for developing an app that is both accurate and reliable.
Stop with the annoying popups
TurnUpTheMusic
Generally a good app but I am losing my mind at opening it up to time my LABOR CONTRACTIONS and having to first click past an irritating notification asking me to tell my pregnant friends about the app. I don’t have any currently pregnant friends and when I do I will not recommend this app.
