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.

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.
What is the best contraction timer app?
ContractionTimer.io is the best for one purpose: helping you track contractions and know when to go to the hospital. Core tracking is free and unlimited. Key factors: ease of use, no ads, accurate calculation, and labor phase detection. ContractionTimer.io covers all of these and supports 18 languages.
This app is not a medical device. Alerts are based on general guidelines like the 5-1-1 rule. Every labor is different. Always consult your healthcare provider. Trust your body.
