Used it throughout a night of contractions and it worked flawlessly. No crashes, no problems, and it was easy to keep track of an average. If there was anything to update about the app, I would want the Summary screen to be able to average based on a time period or number of contractions (average over last 5 contractions or over last hour, etc.) as an average over the entire night can be a little misleading. However, that is looking to the next version - good luck.
