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 wasnt 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.
