The easiest, most accurate way to time your contractions!

Now timing and tracking contractions is as easy as tapping a button. Tap once at the start of the contraction and tap again at the end. Contraction Master automatically keeps track of the start time, duration, and frequency of each contraction. At any time, you can switch to the History screen to see a log of all contractions that have been timed. When contractions are close enough together and long enough Contraction Master can automatically alert you that it's time to go to the hospital and even display a button you can tap to call your Ob/Gyn! If you want to share your contraction history with your doctor or nurse, Contraction Master makes that easy too! You can email or print* your contraction history at any time.

Don't risk showing up to the hospital too early or too late. Join the tens of thousands of people who've used Contraction Master to time their contractions by getting the app today.

Loved It

On the night I went into labor I was not about to start writing down start/end times and doing a bunch of math. Solution - check apps on iPhone to see if there is something to track contractions. Wellah - Contraction Master. This was so convenient and easy to use. I just leaned over and hit start when a contraction started and hit stop when it stopped. It did all the math for me, which lead me to calling my doctor and delivering a child within hours. Definitely recommend and will use for child #2 for sure.
Will probably check out Nursing Master too as I downloaded a different nursing tracking app and it is not very good.

Simple Interface + Valuable App

Intensity of contractions shown through sad face icons is 100% the wrong message to send to mothers during labor. Birth is natural, beautiful process and women shouldn’t be rating their experiences with various sad faces.

The app is simple, easy to use and attractive. Valuable to use during labor.
