3. Record how strong each contraction feels.

Time contractions from your Apple Watch or Lock Screen without unlocking your iPhone.
WHAT DOES A CONTRACTION TRACKER MEASURE?
Duration is how long one contraction lasts. Frequency is the time from the start of one contraction to the start of the next. Interval is the rest time between the end of one contraction and the start of the next.
ContractionTimer.io records these timings automatically as you tap. Contraction strength is based on your own rating of how each contraction feels. Review your history to see changes in timing and reported intensity.

WHAT IS THE 5-1-1 RULE?
The 5-1-1 rule means contractions start every 5 minutes, last 1 minute each, and continue for 1 hour. ContractionTimer.io alerts you when your recorded contractions match this pattern, helping you discuss next steps with your healthcare provider.
A timing pattern alone cannot confirm your stage of labor. Some providers use 4-1-1 or 3-1-1 instead. Ask your provider which pattern applies to you.
WHEN SHOULD I START TIMING?
Start recording when you notice contractions and want to track their pattern. Review duration, spacing, and your reported strength to share a clear history with your care team.

This app is incredible, as it made my life so much easier, and I absolutely loved it! It told me accurately when to pack my bags for the hospital. I appreciated being able to delete a contraction time after I accidentally pressed the button, as this could have ruined the stats. Thankfully, I was able to take sleep during contractions thanks to the relaxation music tracks they included. I downloaded this app to help me keep track of my contractions. I showed the nurse when they started and all the contraction times I had up until we got to the hospital. Thank you for developing an app that is both accurate and reliable.
Amazing
Purple ninja....yeah!
Highly recommend this app- it’s what I used to track contractions for my labor & I was able to use my Apple Watch which made it so much more efficient.
Stop with the annoying popups
TurnUpTheMusic
Generally a good app but I am losing my mind at opening it up to time my LABOR CONTRACTIONS and having to first click past an irritating notification asking me to tell my pregnant friends about the app. I don’t have any currently pregnant friends and when I do I will not recommend this app.
