Contraction Timer & Counter

Use Start and Stop to record each contraction. The timer shows its duration and the time between contraction starts, with alerts for frequent contractions and a recorded 5-1-1 timing pattern.

How to Use This Contraction Timer

When you feel a contraction starting, simply tap the big Start button. The timer will begin counting the duration of your contraction. When the pain or tightening subsides, tap Stop.

The tool will automatically record:

  • Duration: How long the contraction lasted (e.g., 60 seconds).
  • Frequency: The time from the start of one contraction to the start of the next (e.g., 5 minutes apart).

What is the 5-1-1 Rule?

Most doctors and midwives recommend heading to the hospital or birthing center when you meet the 5-1-1 Rule:

  • 5 Minutes Apart: Contractions are coming regularly every 5 minutes.
  • 1 Minute Long: Each contraction lasts for at least 1 minute.
  • 1 Hour: This pattern has been consistent for at least 1 hour.

False Labor vs. True Labor

Not sure if it's the real thing? Use this checklist:

  • True Labor: Contractions get stronger, longer, and closer together over time. They don't stop if you change positions or walk around.
  • Braxton Hicks (False Labor): Contractions are irregular and often stop if you drink water, rest, or change activity. They are usually felt more in the front of the abdomen rather than the back.

When to Call Your Doctor Immediately

Regardless of your timer results, call your healthcare provider if:

  • Your water breaks (especially if the fluid is green or brown).
  • You experience bright red vaginal bleeding.
  • You notice a decrease in your baby's movement.
  • You are less than 37 weeks pregnant (signs of preterm labor).

How timing alerts work

The timer measures contraction duration from Start to Stop and frequency from one start to the next. An early alert uses the last three contractions. The separate 5-1-1 alert requires recorded contractions lasting at least 60 seconds, no more than five minutes between starts, and a continuous recorded span of at least one hour. Timing supports your care plan; it does not establish cervical dilation.
