The tracker does its job well- I'm only docking one star for the data entry interface since it does its primary job well. My wife and I (meaning she) had a very long labor with our baby- out fourth one, 2 weeks overdue, and just reluctant to come out. Active labor went on for days, waxing and waning. This app is better than most of the free ones- it allows you to easily tap to start/stop, tracks to the second, provides moment-to-moment stats as well as overall averages, and makes it easy to track each contraction's severity and add a note (and easy to review the severity info at a glance). The export function produces a great, standard and compliant table easily loaded into Excel or any other app. Overall solid.
Space for improvement: integrated charts and data entry. This app, unlike Almost all others, allows you to edit data so you can backdate/back time a contraction.HOWECER- you can just specify a time A you have to record a contraction that's the right length usin the start/stop button, then enter and edit the start/stop times to what you need. And it tracks to the second (08:10:32) but only let's you edit to the minute which makes it a pain and confusing to enter old data if you start using the app after contractions began. A simple data entry form combined with the current editing for if you start a minute late would be perfect.
Finally, no graphs/charts/plots are available. This is the biggest place that other apps beat it - almost all others will at least provide a line graph of severity, frequency, or duration over time to make visualizing easier. You have to export to another app here.
That said, overall hood for the purpose of having an easy to use tool that accurately and easily tracks start/stop time of contractions, severity, frequency , duration, and allows exporting to other visualizing/analytical tools.
