Contraction Monitor is designed for pregnancy mums to track contractions.

Regular contraction is an importance sign of labor, when that big time is approaching, duration of contraction becomes longer and stronger, frequency becomes shorter. And contractions will show their laws when true labor is coming, so keep tracking contractions will help you distinguish true labor from ‘false’ labor. Graph of contraction duration and frequency makes it easy for you to see the tendency of contractions.

The operation is very easy, just press the button when contraction starts and press the button again when it ends, Contraction Monitor will log the start time, end time, duration and frequency and intensity of this contraction.

Note: You can add only 20 logs in this app, please update to full version which you can add unlimited contractions.

Good app but ads interrupt at very bad times

This app works very well and we used it in preparation of both our children. But I will say one thing: the placement of occasional video ads is INFURIATING. I understand banner ads and small things to pay for a free-ish version, but if you are timing contractions in active labor, you DON'T want to watch a video before proceeding to the next screen.

Designers: Good job on the product and interface. But get a better ad model. Seriously. That's a major UX failure.

This App Takes Advantage of a Desperate Situation

Much like the hardware store that jacks up the price of snow shovels in the middle of a blizzard, so too will this app screw you over at the wrong time. It provides for entry of 20 contractions for free. That lasted about 1.5 hours, and just as my wife started a really painful contraction, this app told me that I had to upgrade, which of course I did. "What's going on, this really hurts," she says. "Hold on honey, just need to enter the credit card info, you doing okay?"

Of course, when you update, your prior information does not port over to the app you just paid for, meaning as your wife is in labor and screaming at the top of her lungs, "What the hell is my frequency?," you can't tell her all that effectively.

Bottom line, do not get the free version of this app. Either pay the $0.99 well in advance (the program was working fine while we used it) or avoid it altogether. A little more disclosure by the designer would have been appreciated. My wife thanks you.

Works as expected!

I downloaded this when my wife woke me up with contractions before the birth of our first child. The app worked great and was just what I needed. It informed me that her contractions were getting closer and closer (4mins when I started 3 when we left for the hospital). The only negative and the reason it wasn't five stars was that after 20 contractions it told me I had to buy it the app for 0.99$ if I wanted to continue (this is an obnoxious time to force me into an app purchase). I did not need to buy the app because it was pretty obvious that labor had started. When we arrived at the hospital, my wife was 5 centimeters and our daughter arrived 4 hours later.
