Health Tracker

Health Tracker is a prototype mobile-phone application that enables women to track and predict their fertility. Users record their monthly cycle information and results of fertility tests in Health Tracker, and the application displays estimates of future fertility based on the entries. Women can use the application to send fertility information to others--for instance, their partner or healthcare provider--and to set up automatic reminders for common tests.

Health Tracker helps people take a more active role in monitoring their health using their mobile phone, which is usually close at hand. We believe Health Tracker's design can serve as a model for other health journaling applications.
