Contraction Timer

Tap once when a contraction starts and again when it ends. The timer records each one and works out the duration and how often they’re coming, so you can see a pattern forming and share clear numbers with your midwife or doctor.

Tap “Start” when a contraction begins.

No contractions timed yet. Tap “Start” when one begins.

The 5-1-1 guide

Many providers say to head in when contractions are about 5 minutes apart, last around 1 minute, and have kept that up for 1 hour — but always follow the advice your own provider gave you.

This timer is a convenience, not medical advice. Call your midwife or doctor with any concern about labour, your waters, bleeding or your baby’s movements.

How it works

Two numbers matter in labour: how long each contraction lasts (duration) and how far apart they are, measured from the start of one to the start of the next (frequency). This timer captures both with a single button and shows a running average of your last few contractions.

Everything is stored only on your device, so you can close the page and come back. When you’re ready, the history table gives you an at-a-glance record to read out over the phone. Always call your provider if you’re unsure — these numbers support that call, they don’t replace it.

Frequently asked questions

When should I go to the hospital? +

A common guide is the 5-1-1 rule: contractions about 5 minutes apart, each lasting about 1 minute, for at least 1 hour. Your provider may give you different instructions — follow theirs, especially if this isn’t your first baby.

How do I measure frequency? +

Frequency is timed from the start of one contraction to the start of the next — not from the end of one to the start of the next. This timer does that for you automatically.

What are Braxton Hicks? +

Braxton Hicks are “practice” contractions that are usually irregular, don’t get closer together, and often ease when you change position or drink water. True labour contractions get longer, stronger and closer together over time.

Should I call my provider? +

Yes — call if contractions follow the pattern they told you to watch for, if your waters break, if you notice reduced movements, bleeding, or you simply feel something isn’t right. Trust your instincts.
