Clear every contraction from the list?
This timer doesn’t tell you when to go: follow the instructions from your health professional or birth centre. If you’re unsure, call Info-Santé 811. In an emergency, dial 911.

How to time a contraction
Tap “Contraction starts” when it begins, then “Contraction ends” when it’s over. The timer records the start time and the duration of each one. The button is large and sits in the middle of the screen so you can use it with one hand, or hand the phone to your partner.
Duration and interval: what the tool measures
- Duration runs from the start to the end of the same contraction.
- Interval runs from the start of one contraction to the start of the next. This is the usual way to count it, and the one you’ll often be asked for on the phone.
- Averages cover the last 3 contractions and those of the last hour, so you can see at a glance whether the pattern is changing.
Tapped by mistake? “Remove last” deletes only the most recent contraction. “Clear all” asks you to confirm before emptying the list.
When to go: follow your instructions
This timer doesn’t tell you when to go. Near the end of pregnancy, your doctor or midwife tells you when to head to your birth centre or hospital: it depends on things like distance, previous births and your health. Write those instructions down ahead of time, for example in your birth plan. Some situations mean leaving right away; your health professional will have explained them.
If you’re unsure, call your birth centre or Info-Santé 811. In an emergency, dial 911.
Your data stays on your device
The list is kept in your browser, on this device only, so nothing is lost if the page reloads. Nothing is sent to Maliah.
Timing together with Maliah
In the Maliah app, the contraction timer is part of the pregnancy profile: your partner sees each contraction live on their phone, past sessions stay in the history, and your birth plan with your instructions is one tap away. You can also log everything by voice, without letting go of anyone’s hand.
Frequently asked questions
How is the interval between contractions measured?
From the start of one contraction to the start of the next. That’s what this tool does, and it’s the measure you’re usually asked for.
Does the timer tell me when to go to the hospital?
No. Follow the instructions from your doctor, midwife or birth centre. If you’re unsure, call Info-Santé 811; in an emergency, dial 911.
What do the averages mean?
The average duration and average interval of the last 3 contractions, then of every contraction that started in the last hour.
I tapped the wrong button: what now?
Tap “Remove last” to delete only the most recent contraction, then carry on.
Are my contractions sent anywhere?
No. They stay in your browser, on this device. Nothing is sent to Maliah.
