Now timing and tracking contractions is as easy as tapping a button. Tap once at the start of the contraction and tap again at the end. Contraction Master automatically keeps track of the start time, end time, duration, and frequency of each contraction. At any time, you can switch to the History screen to see a log of all contractions that have been timed.
