Contraction Timer — Track Labor Contractions Accurately
The Contraction Timer is a free tool designed for expectant mothers in the final stages of labor. It measures the duration of each contraction and the interval between them with a single tap, keeps a full log of all contractions, and automatically alerts you when it's time to head to the hospital based on established medical guidelines.
How to Use the Contraction Timer
- Tap the large button when you feel a contraction begin — the timer starts measuring duration automatically.
- Tap again when the contraction ends — the duration is saved and the interval timer begins counting until the next contraction.
- Repeat with each contraction to build a clear pattern that helps you and your doctor make the right decision.
- Watch the stats at the top: contraction count, average duration, and average interval.
- An automatic alert appears when contractions are 5 minutes apart or less.
What Is the 5-1-1 Rule?
The 5-1-1 rule is the standard medical guideline for when to go to the hospital during labor:
- 5 minutes — between the start of each contraction
- 1 minute — duration of each contraction
- 1 hour — this pattern continues for at least one hour
If this is your second or subsequent pregnancy, your doctor may advise going to the hospital at 7–10 minute intervals, as labor tends to progress faster.
Real Labor vs. Braxton Hicks Contractions
True labor contractions are characterized by:
- Increasing intensity and frequency over time
- Regular, consistent intervals that get shorter
- Not stopping with position changes or rest
- Often starting in the lower back and radiating forward
Braxton Hicks contractions (false labor) are irregular, do not intensify over time, and usually stop with walking or rest. Using this timer makes it easy to distinguish between the two by watching the timing pattern.
When to Go to the Hospital Immediately
- Your water breaks (even if contractions are mild)
- You experience any vaginal bleeding
- Fetal movement significantly decreases or stops
- You feel severe, continuous pain that doesn't ease between contractions
- You are at or before 36 weeks with regular contractions
Tips for Accurate Contraction Tracking
- Start timing from the beginning of the contraction, not at its peak
- Keep your phone nearby for easy tapping during each contraction
- Share the contraction log with your doctor or midwife if requested
- All data is stored locally on your device and never sent anywhere
