I found that this one had two problems. It counted the duration and intervals, but not the time that each contraction was entered (ie. An hour ago, or two?); and, the big one, you need to pay to email the info to your caregiver (which many would find out after they were timing the contractions using this and need to send them). Pretty poor timing to ask someone to pay extra.
