Labor: Contraction Timer на Андроид

Proper birth contractions, in contrast to those first defined by Braxton-Hicks, are designed to shorten the uterine muscles lengthened during pregnancy. During the first stage of labor, contractions appear cyclically and quite regularly every 10-30 minutes and they last for approximately 40 seconds at a time. Towards the end of the first stage, they appear every two minutes and last for 70-90 seconds each. [Wikipedia]

The Labor: Contraction Timer has been designed to help control the frequency and length of contractions in an easy and transparent manner, both during pregnancy and delivery. Thanks to the graph, you can quickly find out whether the contractions are increasing in strength and the option of manually entering the measurement allows you to add previous, unrecorded contractions.

Main features:
- tracking contractions interval and duration
- graphical presentation of contractions on chart
- manually add contraction time and duration
- notification icon while tracking contraction in background
