Your full labor history and contraction progress will be saved regardless of whether you restart the application during a contraction or restart the entire device.
The application is designed to keep track of the times, durations and frequency of the entire labor period.
I created this application for use during my own wife's labor and have paid special attention to keeping the interface as clean and clutter free as possible.
This application is the most convenient way to keep track of your labor contractions.
You have to tap a single button to track the start and end of each of your contractions, and "Full Term" will take care of the rest.
In addition, you get a full featured Fetal Kick counter and a handy pregnancy reference section that you can use to brush up your knowledge.
There is no need to keep this application open the whole time.
Of course, you can also email your contraction history to a health care professional or for your records.
