[iPhone God App] It was found using the Contraction Timer Lite actually

Easily time labor contractions. A handy one-button interface to start and stop the timer, it also lists the duration and spacing of the last contraction, the average and count for the last 20 minutes, and the last hour.

The 20 minute average lets you see if your contractions are increasing or decreasing relative to the last hour. The hour average and count lets you decide when to go to the hospital or birthing center.

The app remembers all data and whether you were in the middle of a contraction or not between launches, so you can jump back and forth between this and your favorite game or another app to distract you during and between contractions.

This is the "Lite" version of my Labor and Contraction Timer app. It has advertisements and is missing the intensity and notes for each contraction, the charts and graphs, and the ability to email contraction data. It is not otherwise limited (you can enter an unlimited number of contractions over an unlimited amount of time.)
