"I was looking for an app that would let my wife start a live activity using a lock screen shortcut, thought it would be impossible to find. This app was perfect during labor!"

"Finally a free timer app that actually has a widget on both the Lock Screen and Apple Watch. Super simple to use and no annoying ads popping up. And if you forget to end the contraction you can go in and edit it."

Panittha, founder of Labora

Hey, I'm Panittha 👋

When I was pregnant with my first baby, I looked for a contraction timer app.

But most apps were full of ads, subscriptions, and poor design.

I wanted a simple, fast, and reliable app that would help me track contractions during labor.

So I built Labora, a simple but powerful contraction timer made for real labor.

With Labora, you can start the timer directly from the Lock Screen, so you don't have to unlock your phone or search for the app.

I hope Labora is as useful to you as it was to me.

FAQ

Got questions?
Here are the answers.

You should start timing contractions when they become regular, noticeable, and uncomfortable. Tracking the timing helps you understand whether labor may be progressing. A contraction timer app like Labora automatically records contraction duration, the time between contractions, and the overall contraction pattern.
To time contractions, record:
  • when the contraction starts
  • when the contraction ends
  • the time between contractions
A contraction timer app like Labora makes this simple. Just start the timer when a contraction begins and stop it when it ends. The app automatically records the duration and interval between contractions and helps you see patterns as labor progresses. Read our full step-by-step guide →
The simplest way to track contractions is with a contraction timer app like Labora. You only need to tap start when a contraction begins and tap stop when it ends. Labora then automatically calculates the contraction duration, the time between contractions, and the overall pattern. You can even start the timer directly from your Lock Screen or Apple Watch.
Many providers suggest the 5-1-1 rule as a guideline for when to contact your doctor or go to the hospital. This means contractions are about 5 minutes apart, last around 1 minute each, and continue for at least 1 hour. Always follow the guidance of your doctor or midwife, especially if contractions become intense or you notice unusual symptoms.
The 5-1-1 rule is a common guideline used to identify active labor. It means contractions are about 5 minutes apart, last around 1 minute each, and continue for at least 1 hour. Tracking contractions with a timer like Labora helps you easily see when this pattern is reached.
Contraction frequency refers to how often contractions occur. It is measured by calculating the time between the start of one contraction and the start of the next. As labor progresses, contractions usually become closer together. A contraction timer like Labora tracks this automatically and shows the interval between contractions for you.
Each contraction is counted from the moment it begins until it ends. Recording each contraction helps you see how long they last and how close together they are. Watching these patterns can help you understand how labor may be progressing. A contraction timer app like Labora makes this easier by automatically recording each contraction and organizing the timing for you.
A common guideline is the 5-1-1 rule: contractions about 5 minutes apart, lasting around 1 minute each, for at least 1 hour. However, every pregnancy is different — your provider may give you a different threshold based on your situation and how far you live from the hospital. Always follow their specific guidance. Labora lets you set your own rule so the alert fires exactly when your provider says. Learn more about the 5-1-1 rule and when it applies →
In early labor, contractions typically last between 30 and 45 seconds and occur every 5 to 20 minutes. As labor progresses into active labor, contractions usually become longer, stronger, and closer together. Tracking duration with a contraction timer helps you notice these changes over time.
