Contraction Timer

Tap once when a contraction starts and again when it ends. We track how long each one lasts, how far apart they are, and whether you have hit the 5-1-1 pattern, so you know when it might be time to head to hospital. Your timing is saved on this device, so you will not lose it if the screen locks.

Call your hospital or go in now, even if you are not at 5-1-1, if: your waters break (especially if the fluid is green, brown or smells bad), you have heavy bleeding, constant severe pain you cannot talk or walk through, a bad headache or vision changes, your baby is moving less than usual, you feel feverish or faint, or you have any signs of labour before 37 weeks.

How to time contractions

  1. Tap "Start" the moment a contraction begins (your bump tightens).
  2. Tap again to stop when it eases off. That gives you the length (duration).
  3. The "apart" time (frequency) is measured from the start of one contraction to the start of the next, so it includes the rest in between.
  4. Time several in a row, ideally for an hour, so a pattern can show. Tag each one Mild, Moderate or Strong if you like.

A common mistake is timing from the end of one contraction to the start of the next, that under-counts the frequency. Always go start to start, which this timer does for you.

The 5-1-1 rule (and 4-1-1, 3-1-1)

For a low-risk, full-term first pregnancy, the usual guide is 5-1-1: contractions about 5 minutes apart, each lasting about 1 minute, for at least 1 hour. That is often when active labour is established and it is time to head in.

Your team may tell you to use 4-1-1 or 3-1-1 instead (every 4 or 3 minutes) if this is not your first baby, you had a fast previous labour, you are expecting twins, you are planning a VBAC, or you live far from the hospital. Always follow the advice your own doctor or hospital gave you.

True labour or Braxton-Hicks?

True labourBraxton-Hicks (false)
PatternRegular, come closer togetherIrregular, no real pattern
StrengthGet steadily strongerStay the same or fade
With movementContinue through walking or restOften ease if you move or rest
Where you feel itOften start in the back, wrap to the frontUsually front-of-belly tightening
EffectOpen (dilate) the cervixDo not dilate the cervix

Braxton-Hicks are often triggered by dehydration, so have a drink, rest, and re-time. If they settle, it was likely a false alarm.

The stages of labour

  • Early labour: cervix opening up to about 6 cm. Contractions are milder and more spaced out (often 5 to 20 minutes apart). This stage can last many hours, usually best spent resting at home.
  • Active labour: cervix from about 6 to 10 cm. Contractions become strong and regular, roughly 3 to 5 minutes apart and around a minute long. This is usually the time to be at the hospital.
  • Transition and pushing: fully open at 10 cm. Contractions are intense and close, every 2 to 5 minutes.
  • Delivering the placenta: mild contractions shortly after your baby is born.

What to do during early labour at home

If contractions are still far apart and manageable, you usually do not need to rush in. Rest between contractions, stay hydrated, have a light snack, take a warm shower, and keep timing. Save your energy for active labour.

Frequently asked questions

What is the 5-1-1 rule?

Contractions about 5 minutes apart, each lasting about 1 minute, sustained for at least 1 hour. For a low-risk full-term pregnancy, that is the classic sign it is time to go to hospital. Some mums are told to use 4-1-1 or 3-1-1 instead.

How do I time contractions correctly?

Tap start when one begins and stop when it eases. Frequency is measured start-to-start (including the rest in between), and duration is start to end. Time several over about an hour so a pattern shows.

How do I know if it is real labour or Braxton-Hicks?

True contractions are regular, get closer and stronger, and continue whether you move or rest. Braxton-Hicks are irregular, do not get closer, and often ease when you move, rest or drink water.

When should I go to hospital sooner than 5-1-1?

Go in or call straight away if your waters break, you have heavy bleeding, constant severe pain, reduced fetal movement, severe headache or vision changes, or any labour signs before 37 weeks.

It is my second baby, should I wait for 5-1-1?

Not necessarily. Later labours can move faster, so many doctors advise going in earlier, for example at 4-1-1. Follow the guidance your own hospital gave you.

My contractions are irregular, am I in labour?

Irregular tightenings that do not get closer or stronger are often Braxton-Hicks or early labour. Keep timing, hydrate and rest. If they become regular and stronger, log them here.

Does this timer save my data?

Yes, on this device only. It is stored in your browser so a screen lock or refresh will not lose your log, and nothing is ever uploaded. Use "Clear all" to wipe it.

Can this timer tell me I am in labour?

No. It tracks the pattern, but only a midwife or doctor can confirm labour and check how dilated you are. Use it to inform the call you make to your hospital.
